Lightning-sparked wildfires rage across Oregon and Washington after mid-July severe storms

Three of the Northwest's most impactful wildfires were ignited by lightning during a mid-July outbreak of thunderstorms across Oregon and Washington.

Wildfires ignited by mid-July severe weather continue to spread across Oregon and Washington as persistent heat, dry fuel and gusty winds challenge firefighters across the mountainous terrain of the Northwest.

The three largest and highest-priority wildfires burning across the region all share a common origin: lightning.

WHY DRY THUNDERSTORMS POSE WILDFIRE, DUST STORM RISKS

A series of dry thunderstorms swept across the Pacific Northwest in mid-July, producing thousands of lightning strikes that ignited dozens of wildfires across Oregon and Washington, according to the National Interagency Fire Center (NIFC) and regional incident management teams.

Dangerous fire weather ranging from hot temperatures, dry vegetation, low humidity and gusty winds allowed the lightning-sparked fires to spread rapidly across the region.

As of Sunday, the NIFC reported 52 large wildfires burning across the Northwest, including 42 in Oregon that have burned hundreds of thousands of acres in total. Fire officials also reported 15 new fire starts and five new large incidents over the previous 24 hours as wildfire activity remained elevated across the region.

HOW THE LAY OF THE LAND AFFECTS WILDFIRE BEHAVIOR

The surge in wildfire activity prompted the NIFC to raise the nation to Preparedness Level 5 — the highest level on the five-tier scale —on July 18. The designation remains in effect until wildfire activity and the demand for crews, aircraft and equipment decline nationwide.

Rowe Creek Complex

As the region's largest active fire, the Rowe Creek Complex fire has burned over 200,000 acres in north-central Oregon.

The Rowe Creek Complex was sparked by lightning on July 15 and has since grown into one of the largest active wildfires in the country, fueled by hot, dry conditions and wind-driven fire behavior.

According to the latest update from the Rowe Creek Complex Incident Management Team, the wildfire has scorched 208,758 acres and is 31% contained, as more than 1,100 firefighters continue working to strengthen containment lines ahead of another day of critical fire weather.

According to the Oregon State Fire Marshal, the fire is burning across Wheeler, Wasco and Crook counties, about 10 miles south of Fossil, in central Oregon, and has triggered hundreds of evacuations across impacted areas. 

The Rowe Creek Complex consists of multiple lightning-caused fires sparked by thunderstorms on July 15.

As the fires grew, several merged into the Crosswhite Fire, which has since become the largest fire in the complex, according to the Rowe Creek Complex Incident Management Team.

The Rowe Creek Complex has also impacted portions of the Ochoco National Forest, prompting the U.S. Forest Service to expand emergency closures across national forest lands, roads and trails as firefighters continue to battle the blaze.

Akawa Butte Fire

While the Rowe Creek Complex continues to dominate the Northwest in size, the Akawa Butte Fire has become the region's most pressing wildfire threat because of its proximity to homes and communities in Central Oregon.

Dubbed the nation's top firefighting priority by the National Interagency Fire Center, more than 1,000 firefighters are battling the Akawa Butte Fire near Sisters, a small mountain community about 20 miles northwest of Bend.

The Akawa Butte Fire has destroyed two homes as firefighters work to protect additional residences and infrastructure near Sisters.

According to the Oregon State Fire Marshal, the fire has burned 26,435 acres and is 5% contained as of the latest update.

THE COMPLEX RELATIONSHIP BETWEEN WILDFIRES AND WILDLIFE

The Akawa Butte Fire was sparked by lightning during a series of thunderstorms that ignited multiple fires across Central Oregon in mid-July.

Kaiser Canyon Fire

While Oregon is home to the Northwest's two largest wildfire priorities, neighboring Washington is battling a major blaze of its own.

The Kaiser Canyon Fire has grown into the state's largest active wildfire, scorching more than 110,000 acres on the Colville Indian Reservation in north-central Washington.

WHAT IS THE HAINES INDEX?

According to the Kaiser Canyon Fire Incident Management Team, the lightning-caused wildfire has burned 110,355 acres and is 12% contained. More than 760 personnel are assigned to the incident as firefighters continue working to strengthen containment lines.

The Kaiser Canyon Fire was sparked by lightning on July 16 and is burning in Okanogan County in north-central Washington, according to InciWeb.
