Louisiana State Police and other authorities are monitoring ongoing flooding through Avoyelles Parish as the area sees rising waters.
Troopers said similar flooding conditions are also being experienced in other areas across Louisiana as the remnants of Arthur continue to impact the state.
As part of response efforts, authorities are conducting door-to-door assessments to evaluate the impact of flooding on residents and their properties.
They're also providing assistance to residents in affected areas by helping address immediate needs to ensure their safety, officials said.
"Residents are encouraged to remain weather aware and monitor local conditions," state police said on Facebook.
Troopers also advise people to avoid unnecessary travel and never drive through flooded roadways or around barricades.
FOX Weather Field Correspondent Robert Ray is live in Montgomery, Alabama, where a dangerous flood threat is unfolding across the South. At the same time, severe storms are creating an additional weather hazard, putting millions of people at risk from flooding, damaging winds and other dangerous conditions.
Over three million people fall under a recently issued Severe Thunderstorm Warning impacting the Atlanta, Georgia, area.
Wind gusts could reach up to 60 mph. Clayton, Fayette, Fulton and Henry counties are under the alert, which remains in effect through 5 p.m.
{{#rendered}}A dam in Mississippi has failed and a Flash Flood Emergency is in effect, causing evacuations as Arthur's remnants slam the South.
The National Weather Service said Anchor Lake Dam has failed on the East Hobolochitto Creek in Pearl River County.
At 3 p.m., emergency management officials reported the failure of the dam, causing flash flooding downstream on the creek, the National Weather Service said.
People living in areas downstream from Anchor Lake Dam along the East Hobolichitto Creek need to evacuate immediately.
Officials are also advising people to seek higher ground as soon as possible.
The National Weather Service said this is an extremely dangerous and life-threatening situation.
People in the area should avoid travel unless they're fleeing an area subject to flooding, or under an evacuation order.
Port-Tropical Cyclone Arthur has brought significant damage to the New Orleans area today.
Jefferson Parish Councilman Scott Walker posted video to social media in which he shows train cars that were tilted off their tracks in Metairie due to the storm.
The footage also shows trash strewn across the ground at a nearby service area.
The storm destroyed homes and tore down power lines, too, according to local reports.
The National Weather Service has issued a Flash Flood Warning for the area and warned that life-threatening flooding is occurring in nearby Picayune, Mississippi.
Extensive damage is being reported across Slidell, Louisiana, as the remnants of Arthur continue to impact the state.
The Slidell Fire Department shared images of damage in the city's Eden Isles subdivision. The city is located about 30 miles from New Orleans.
Trees are toppled and there appears to be damage to homes in the area.

The National Weather Service New Orleans said preliminary surveys have found that an EF-1 tornado with top winds of 95 mph impacted Houma.
A second EF-1 tornado has been confirmed on the West Bank of Jefferson Parish, with max winds of 90 mph, according to the National Weather Service.
{{#rendered}}The threat of severe weather from Arthur’s volatile remnants is expanding eastward into the afternoon.
The Storm Prediction Center has issued a widespread Tornado Watch until 11:00 p.m. ET tonight, encompassing metropolitan Atlanta, a massive portion of southern Alabama, and the western Florida Panhandle.
As the center of the post-tropical low pressure system edges further inland, its outer feeder bands are tapping into an environment loaded with extreme tropical moisture and strong low-level atmospheric shear.
These conditions are highly favorable for the development of fast-moving, low-topped supercell thunderstorms.
Because these tropical storms pull directly from Gulf moisture, any spin-up tornadoes that develop will likely be heavily rain-wrapped and exceptionally difficult to spot visually until they are right on top of you.
Residents across the watch area—including major corridors along Interstate 85 in Georgia and Interstate 10 in Florida—are strongly urged to review their severe weather safety plans immediately.
Ensure you have multiple ways to receive warnings that can wake you up tonight, keep your mobile devices charged, and be ready to seek shelter in an interior room on the lowest floor of a sturdy building the moment a warning is issued for your area.
As a historic and life-threatening flash flood disaster grips the central Gulf Coast and expands across the Southeast, we need your help to safely document the sheer scale of this crisis.
Your real-time visuals are incredibly vital. They help us show everyone the true magnitude of this catastrophic tropical deluge, keep communities informed, and aid forecasters tracking these rapidly shifting hazards.
Visible satellite imagery today is painting a stunning, albeit terrifying, picture that perfectly explains why torrential tropical thunderstorms have stubbornly refused to move over central Louisiana, leading to a truly historic disaster.
The high-resolution images reveal the exact atmospheric engine driving the catastrophic flooding in Avoyelles Parish and neighboring communities.
As the center of what is now post-tropical "ex-Arthur" ground slowly to the northeast, it set up a textbook zone of surface convergence directly over central Louisiana.
This convergence zone created a violent, invisible boundary where two completely opposing wind patterns collided from the North with cooler northwest winds on the backside of the low, and from the South with a ferocious, 45-to-60 mph low-level wind jet blowing directly ahead of the storm center.
Because those strong southerly winds were drawing straight from the ultra-warm waters of the Gulf of America, they acted as a non-stop, high-velocity atmospheric firehose, relentlessly pumping record-level tropical moisture right into the collision zone.
When that infinite moisture supply slammed into the opposing northwesterly winds, the air had nowhere to go but straight up.
Because this boundary has remained locked in place, it forced thunderstorms to continuously form, collapse, and reform over the exact same patches of land—a dangerous meteorological phenomenon known as backbuilding and training.
The math behind this setup is as simple as it is devastating: an unrelenting moisture feed combined with a stalled atmospheric boundary equals more than 2 feet of rain in less than 24 hours.

As if the historic, ongoing flash flooding wasn't enough, the National Weather Service in New Orleans has confirmed that at least three separate tornadoes touched down across southeast Louisiana during Arthur’s severe weather blitz.
While meteorologists stress that these findings are preliminary and survey teams are still assessing the damage, the NWS has confirmed the following tracks and intensities:
Tornado #1 (Houma): Rated an EF-1 with peak estimated winds of 95 mph.
Tornado #2 (West Bank of Jefferson Parish): Rated an EF-1 with peak estimated winds of 90 mph.
Tornado #3 (East Bank of Jefferson and Orleans Parishes): Rated an EF-1 with peak estimated winds of 95 mph.
These fast-moving, rain-wrapped tropical vortices spun up quickly within Arthur's intense outer convective bands. Even at EF-1 strength, winds nearing 100 mph are more than capable of snapping power poles, peeling roofing material off homes, flipping unanchored structures, and tossing heavy debris.
With survey crews still active in the field, it is highly possible that these track lengths may be extended or additional tornado touchdowns will be confirmed in the coming days.
An absolute worst-case scenario is unfolding in Louisiana as the National Weather Service continues its Flash Flood Emergency for Southern Avoyelles Parish.
An unfathomable 12 to 24 inches of rain has already fallen across the region, completely overwhelming the landscape and triggering active, widespread emergency evacuations.
Meteorologists have classified this as a Particularly Dangerous Situation. Intense tropical training thunderstorms have essentially dropped two feet of water over areas that are completely incapable of draining it, forcing residents from their homes as water reaches catastrophic levels.
The true severity of the Flash Flood Emergency in Picayune, Mississippi, is hitting home on social media.
Local resident Angelina Rushing posted a distressing video to Facebook from the corner of West Canal Street, describing the exact moment the local storm drain simply stopped working minutes prior, causing water to instantly back up and inundate the area.
{{#rendered}}The ongoing, life-threatening flash flood disaster across the central Gulf Coast has forced meteorologists at the Weather Prediction Center to expand the rare Level 4 out of 4 "High Risk" zone today.
Short-range computer models and real-time radar data confirm a worst-case scenario is unfolding as repetitive bands of "backbuilding" storms—where intense rain continuously reforms over the exact same locations—have already dropped a staggering 9 to 11 inches of rain across parts of Louisiana and Mississippi.
The environment fueling these storms is historically volatile. The atmospheric engine is drawing directly from record-breaking tropical moisture levels (precipitable water values over 2 inches) and a ferocious 45-to-58 mph low-level wind jet pumping juice straight off the warm Gulf of America.
Because of this, forecasters have modified today's risk map in two critical directions:
Westward expansion: Pushed deeper into central Louisiana, where a Flash Flood Emergency remains actively underway due to ongoing, catastrophic inundation.
Northeastward expansion: Expanded across southern Mississippi and Alabama, where high-resolution modeling warns that an additional 5 to 8+ inches of rain is highly probable.
The WPC notes this dangerous flood corridor will continue to expand deeper into the Southeast as the afternoon progresses.
Heightened life-safety concerns are now shifting dynamically into southwestern and central Georgia, as well as further north into the highly vulnerable terrain of the southern Appalachians.
If you are anywhere within this expanding bullseye, do not wait for water to enter your home—take action to protect your life immediately.
The National Weather Service has issued a rare Flash Flood Emergency for Stone County, Mississippi until 4:15 p.m. CT this afternoon.
Local emergency management officials report that a catastrophic crisis is unfolding, with significant to major flooding occurring across the entire county, forcing active high-water rescue operations.
A staggering 6 to 10 inches of rain has already fallen, and with Arthur's relentless tropical bands stalled over the area, an additional 3 to 6 inches of rain is highly likely.
Meteorologists have classified this as a Particularly Dangerous Situation. The ground is completely saturated, meaning any additional rainfall will instantly become dangerous, rushing runoff. People within the warning area are urged to seek higher ground immediately and strictly avoid all travel.
The Flash Flood Emergency in Pearl River County has triggered a major transportation crisis, forcing the total closure of Interstate 59 in both directions near Picayune.
Muddy floodwaters fueled by Arthur's relentless tropical remnants have breached the highway, submerging all travel lanes under feet of water.
Mississippi Department of Transportation crews and state troopers have shut down the corridor, diverting all traffic off the interstate.
Officials warn that the highly unusual closure will remain in effect indefinitely until the training rain bands subside and water levels recede below the asphalt.
{{#rendered}}The escalating Flash Flood Emergency in Avoyelles Parish has reached a critical, life-threatening stage as torrential tropical rain from Arthur’s stalled remnants completely submerges towns across central Louisiana.
Local emergency services are stretched to their limits trying to manage a rapidly deteriorating crisis. In Mansura, the Louisiana Department of Transportation has officially shut down LA Highway 114, which has become completely impassable due to deep, fast-moving floodwaters swallowing the asphalt.
Conditions are equally dire to the east. Streets throughout Simmesport are entirely underwater, stranding residents and inundating yards as neighborhood drainage systems stand completely overwhelmed by the sheer volume of water.
The gravity of the situation was felt this morning in nearby Cottonport, where emergency dispatchers confirmed a high-water rescue operation had to be initiated to save individuals trapped by rapidly encroaching waters.
First responders are reiterating that all residents should remain safely on high ground and strictly avoid any travel, as conditions continue to worsen by the hour.
A startling video posted to Facebook by local resident Nayy Booth showcases the severe reality of the ongoing Flash Flood Emergency along the Gulf Coast, capturing deep, muddy floodwaters completely swallowing portions of US Highway 11 in Picayune.
The video highlights an increasingly dangerous travel environment as torrential downpours from Arthur’s remnants rapidly transform major thoroughfares into virtual rivers.
The catastrophic situation in Picayune, Mississippi, is on the verge of deteriorating even further as the FOX Forecast Center tracks a new, heavy band of tropical downpours pushing directly into the city.
Picayune and wider Pearl River County are already paralyzed under a rare Flash Flood Emergency after a grueling 7 inches of rain fell in less than six hours earlier today.
The ground is completely maxed out and incapable of absorbing a single additional drop of water, meaning this incoming round of intense precipitation will instantly convert into dangerous, rushing surface runoff.
Emergency management officials are reiterating their urgent warnings for all residents to stay exactly where they are on high ground, as any attempt to travel through this next wave of water will put lives at severe risk.
{{#rendered}}FOX Weather Correspondent Brandy Campbell is reporting live from Biloxi, Mississippi, where the coastal community is bracing for the brunt of Arthur’s remnants under a maximum Level 4 out of 4 excessive rain risk.
A live MDOT traffic camera on Mississippi Highway 11 captures a visual of the escalating crisis in Picayune this morning, showing floodwaters submerging portions of the busy thoroughfare.
With the city already paralyzed by nearly 7 inches of rain that fell in less than six hours, officials are monitoring these live cameras to track rapid water rises and are strongly imploring residents to stay home as emergency crews navigate the worsening deluge.
A Flash Flood Emergency is the highest, most urgent alert issued by the National Weather Service, reserved exclusively for rare situations where catastrophic, life-threatening flooding is actively occurring.
Unlike a standard Flash Flood Warning—which means flooding is possible or developing—an Emergency is only triggered when severe flooding poses an immediate threat to human life or indicates a major structural disaster is underway, such as a dam failure or widespread water rescues.
When an Emergency is declared, it means infrastructure is failing, roads are completely submerged, and residents must take immediate, extraordinary action to protect their lives, such as moving to the highest floor of a building or seeking immediate high ground.
{{#rendered}}The National Weather Service has issued a life-threatening Flash Flood Emergency for Pearl River County in southern Mississippi as the moisture-packed core of Arthur's remnants stalls directly over the region.
Local emergency management officials report that catastrophic flooding is actively occurring, with multiple roads completely submerged, impassable, and hazardous to motorists.
A staggering 3 to 5 inches of tropical rain has already inundated the area this morning, and with the persistent feeder bands showing no signs of budging, forecasters warn that an additional 3 to 6 inches of rain is entirely possible through the afternoon.
Residents are being strongly urged to seek higher ground immediately and stay completely off local roadways, as rapidly rising waters are creating extremely dangerous conditions across the county.
The National Weather Service has issued a rare and life-threatening Flash Flood Emergency for Avoyelles Parish as the core of Arthur’s tropical remnants unloads catastrophic rain rates across central Louisiana.
Emergency officials report that relentless training thunderstorms have overwhelmed local drainage systems, causing rapid, severe water rises that are actively inundating roadways and threatening low-lying residential structures.
The FOX Forecast Center says rain is falling at 1-3 inches per hour with radar estimating more than a foot of rain has fallen in the past few hours.
The National Hurricane Center has officially written the final chapter on Arthur’s life cycle as a named tropical cyclone.
In its final advisory issued late Wednesday night, the NHC discontinued all coastal Tropical Storm Watches and Warnings after the system's heavily sheared center erratically relocated over land near Galveston, Texas, and collapsed into a post-tropical remnant low pressure area with maximum sustained winds of 35 mph.
While its status as a tropical storm lasted less than 24 hours, the NHC's parting message was a stark warning to the South: Arthur's structural demise changes absolutely nothing about the sheer volume of water it is carrying.
Right now, Arthur’s decaying ghost is silently gliding northeastward over Mississippi.
Even though the low-level circulation is rain-free, the storm's massive wind field is drawing significant amounts of moisture off the Gulf of America.
[image gallery]
This setup has effectively parked an atmospheric firehose directly over Mississippi and Alabama, where intense tropical training bands will continue to dump torrential downpours through Friday.
Arthur may no longer be a tropical storm on paper, but its remnants are actively delivering the exact catastrophic, multi-day flood disaster that forecasters feared most.
{{#rendered}}The threat of dangerous, spin-up tornadoes is escalating across southern Mississippi and Alabama today as the volatile outer feeder bands of Arthur’s remnants drill into the Gulf Coast.
The FOX Forecast Center warns that intense atmospheric shear—the changing of wind speed and direction with height—is overlapping with a deeply unstable, moisture-rich tropical air mass pushing inland.
This combination will make it incredibly easy for rotating, low-topped supercell thunderstorms to spawn quick, fast-moving tornadoes with very little warning through the afternoon and evening hours.
Because these tropical twisters are often wrapped in torrential rain and difficult to see ahead of time, experts are urging residents from Biloxi to Mobile to keep their devices charged, have multiple ways to receive severe weather alerts, and review their emergency shelter plans immediately.
A volatile situation is unfolding across Mississippi right now as the severe outer feeder bands of Arthur’s remnants spawn multiple tornadoes simultaneously.
The National Weather Service has issued multiple Tornado Warnings with at least two confirmed twisters happening in the southern part of the state.
Dramatic video captured early this morning in Montegut, Louisiana, showcases the ferocious power remaining in Arthur's remnants as they pushed through the coastal bayou communities.
The video reveals blinding tropical downpours driving sideways under violent, howling wind gusts that slammed Terrebonne Parish well before sunrise.
{{#rendered}}A dangerous situation is developing in Hattiesburg, Mississippi, which has just been placed under a Flash Flood Warning as downpours from Arthur’s remnants stall over the Pine Belt.
FOX Weather Meteorologist Haley Meier is reporting live from the ground, tracking downpours that are rapidly blinding drivers and pooling across major thoroughfares.
The FOX Forecast Center has taken the rare step of upgrading the FOX Weather Threat Zone to an "extreme" designation right along the Gulf Coast today.
This maximum threat area places coastal Mississippi, southern Alabama, and the western Florida Panhandle directly in the crosshairs for catastrophic flash flooding as Arthur's tropical remnants stall.
A relentless onslaught of tropical moisture from Arthur's remnants has inundated southeastern Louisiana and southern Mississippi with staggering rain totals this morning.
The FOX Forecast Center reports that radar estimates show more than 8 inches of rain has already fallen in isolated spots south and west of New Orleans, forcing widespread flash flooding.
The core of the heaviest rain is now actively shifting eastward into southern Mississippi, where saturated ground will quickly trigger rapid water rises along roads and creeks through the afternoon.
{{#rendered}}A suspected tornado spun up by the outer bands of Arthur’s remnants has left a visible trail of destruction in the Lakeshore Village subdivision of Slidell, Louisiana.
Pictures on social media show snapped large trees, shredded backyard fences, and downed active utility lines across local streets.
Emergency crews are working to secure the area and clear the debris, while officials continue to urge locals to stay indoors and treat all downed wires as live.
The brutal combination of torrential rain, tornadoes, and strong winds from Arthur's remnants has knocked out power to tens of thousands of residents across the Gulf Coast this morning.
According to data from PowerOutage.com , nearly 40,000 customers are currently sitting in the dark across Louisiana, while more than 14,000 utility customers are experiencing outages in neighboring Texas.
Emergency crews are working to restore electricity as quickly as possible, though ongoing severe weather and flooded roadways are presenting significant challenges for line workers.
When the Weather Prediction Center (NOAA) highlights a region in a Level 4 "High Risk" for excessive rain, it is a designation that should make everyone in its path stop what they are doing.
These alerts are not issued lightly; in fact, the Weather Prediction Center only triggers a Level 4 risk on roughly 4% of days out of the entire year nationwide.
It is the highest and most urgent tier on the flash flood threat scale, reserved exclusively for atmospheric setups that are primed to deliver historic, catastrophic rain rates capable of overwhelming modern infrastructure and completely shifting the terrain within hours.
The statistics behind these rare declarations are staggering. Data compiled by NOAA over an 11-year period reveals that while High Risk days happen just 4% of the time, they account for an astonishing 36% of all flood-related fatalities and 80% of all flood-related property damages in the United States.

A Level 4 alert essentially means meteorologists are no longer just forecasting generic roadway ponding—they are predicting major structural inundation, widespread water rescues, and life-threatening conditions.
{{#rendered}}The National Weather Service has issued a rare Particularly Dangerous Situation (PDS) Tornado Warning for St. Tammany Parish as a "large and extremely dangerous" tornado moves directly through the Slidell area.
A radar-confirmed tornado was tracked on radar pushing northeast at 25 mph, forcing immediate life-safety shelter orders for Pearlington and the Stennis Space Center.
As if a high-level flood threat across the Deep South wasn't enough, the weather system that refuses to quit could have a second act waiting in the wings.
The FOX Forecast Center is actively tracking the remnants of Arthur as the parent trough of low pressure crawls across the Southeast.
According to the National Hurricane Center, environmental conditions appear marginally conducive for some subtropical or tropical redevelopment on Friday or Saturday.
The entire system is projected to accelerate northeastward over the next 48 hours, eventually emerging off the East Coast of the United States and spilling out into the warm waters of the Western Atlantic Ocean.
[image gallery]
While the possibility of Arthur’s atmospheric ghost reforming at sea is drawing the attention of meteorologists, forecasters emphasize that it changes nothing about the immediate, high-stakes threat on land.
Regardless of whether the system regains a tropical name or structure over the ocean this weekend, its current footprint remains incredibly dangerous.
The immediate focus stays locked on the massive shield of tropical moisture currently swamping the Southeast, where torrential downpours retain the full potential to unleash widespread, life-threatening flash flooding through the next day or two.
FOX Weather Meteorologist Haley Meier is reporting live from the ground in Hattiesburg, Mississippi, this morning, where a high-risk flood threat is rapidly unfolding.
You can watch Haley Meier reporting on the severe weather threat all day on FOX Weather to see how the situation unfolds.
{{#rendered}}While devastating flash flooding remains the primary hazard from Arthur's remnants, the storm system is packing an extra punch with a persistent tornado threat across the Deep South today.
The Storm Prediction Center has outlined a severe weather risk area spanning southeastern Louisiana, southern and central Mississippi, Alabama, and parts of the Florida Panhandle.
As a weak surface low and atmospheric wave pull deep tropical moisture into the region, the wind field is ramping up significantly.
This high amount of low-level wind shear colliding with very sticky, mid-70s dewpoints will create an environment where rotating supercell thunderstorms can easily spin up tornadoes with little warning.
The risk is expected to peak through this afternoon and into early tonight as peak daytime heating maximizes atmospheric instability, making it critical for residents to keep their phones charged and weather alerts turned on.
Emergency officials are on the ground assessing damage this morning after a suspected tornado spun up in the outer bands of Arthur's remnants, tearing through parts of the New Orleans metro area.
The FOX Forecast Center reports that the fast-moving storm showed significant rotation as it pushed past New Orleans International Airport and neighboring communities just before dawn, triggering urgent Tornado Warnings across Jefferson and St. Charles parishes.
While the immediate threat has shifted eastward, crews are currently navigating heavily flooded streets to clear downed trees, check on ruptured power lines, and survey structural damage in the hardest-hit neighborhoods.
Kenner Police Chief Keith Conley is urging residents to shelter in place and stay entirely off local roads as torrential rain from Arthur's remnants rapidly floods intersections.
Officials emphasize that driving through submerged streets not only stalls out vehicles but creates wakes that push floodwaters directly into nearby homes.
{{#rendered}}A Flash Flood Warning has been issued for the New Orleans metro area as a brutal, slow-moving band of tropical thunderstorms slams southeastern Louisiana this morning.
The FOX Forecast Center notes that radar estimates show more than 5 inches of rain has already inundated areas just west of downtown, with rain rates pounding the pavement at an astonishing 2 to 4 inches per hour.
With the city’s drainage infrastructure being pushed to its absolute absolute limits by Arthur's moisture, residents are strongly urged to stay off the roads, avoid low-lying underpasses, and monitor localized rising water immediately.
[image gallery]
Right now, the Deep South is bracing for a highly dangerous, multi-day weather event as the relentless remnants of Arthur tap into a powerhouse combination of Pacific and Gulf moisture.
The FOX Forecast Center says a rare Level 4 out of 4 high risk for flash flooding has been issued for Thursday, followed by a Level 3 risk on Friday, signaling that widespread and locally catastrophic flooding is likely.
The atmospheric plume is loading up a corridor from eastern Texas all the way to Georgia, putting millions of people directly in the crosshairs.
Flood Watches blanket major metro areas including New Orleans, Baton Rouge, Jackson, Montgomery, and Atlanta, where the ground is fast approaching a breaking point.
While a broad swath of the South can expect a general 5 to 8 inches of rain, the bullseye sitting over Louisiana, Mississippi, and Alabama is tracking a much more severe threat. A broad corridor through these states is likely to see 8 to 12 inches of rain, with localized totals easily carving past a foot where the heaviest tropical rainbands stall.
