Images captured by Maxar show the storm surge impact in Ozello and Crystal River on Wednesday – about 100 miles south of the storm's landfall.
Storm surge reached 7 feet in Cedar Key, about 40-50 miles away from Crystal River, setting its highest storm surge mark and breaking the old record set by Hurricane Hermine in Sept. 2016.
By early Wednesday morning, the storm surge in Tampa Bay and Clearwater had reached over 3 feet, and additional water continued to rush in during high tide.
As the day progressed, Idalia lost strength and was downgraded to a tropical storm as it moved towards Georgia and South Carolina.
The storm caused a storm surge in Charleston, South Carolina, with winds reaching up to 40 mph pushing water from the Atlantic Ocean onto the city streets.
The National Weather Service confirmed on Wednesday evening that water had breached the Charleston Batters, which is the seawall in Charleston. Major coastal flooding was also observed in downtown Charleston as well as Edisto Beach. Water levels reached the fifth-highest levels in Charleston, and highest since Hurricane Irma in 2017.
