However, wind advisories remain across much of the region for sustained winds.
Communities on the U.S. Gulf Coast are bracing as Hurricane Isaias made landfall Friday night as a Category 2 storm.
The storm, with winds up to 105 mph, made landfall near Destin, Florida, in the Florida Panhandle at 8:30 p.m. CT. As it continued its march north over the western part of the Panhandle, the storm weakened to a Category 1 and then to a post-tropical cyclone early Saturday.
At least four deaths from the storm were confirmed, according to officials, including two in Florida and two in Alabama.
Ahead of the storm, many low-lying and coastal areas were under evacuation orders, Florida Gov. Ron DeSantis said in a press conference Friday morning.
Storm surge warnings were also in place along the coast, with surges forecast to reach up to 9 feet from the Santa Rosa/Okaloosa County Line, Florida, to Grayton Beach, Florida.
Over 840,000 customers are without power on Saturday with the majority of outages in Florida.
In Florida, 438,137 customers are without power; in Alabama, 294,662 customers are without power; and in Georgia, 111,105 customers are without power, according to Poweroutage.us.
There are no confirmed fatalities from Hurricane Isaias in the state of Florida, Gov. Ron DeSantis said Saturday.
The governor had said they are hearing about a possible fatality in Escambia County from a fallen tree -- but that has not yet been confirmed by state officials, he said.
"We have not yet received any requests for search and rescue deployment, and I take that as an optimistic sign. But our resources are prepared in the event that the need arises, particularly with respect to any flooding that may occur on the back end of this storm," DeSantis said.
There were wind gusts of up to 116 mph near the Santa Rosa sound, DeSantis said, and over 100 mph near Pensacola. Water Levels were 5.5 feet higher than normal, he said.
All state-owned bridges are safe and have been reopened for travel after having been inspected his morning, he said. Northwest Florida Beaches Airport has reopened, but Destin Fort Walton Beach Airport is still closed.
Flash and urban flooding will remain likely across the region, with considerable impacts possible across much of southern Alabama and the Florida Panhandle into southwestern Georgia as well as for parts of southern Appalachia and the coastal Carolinas.
River flooding is also expected, some of which could be significant.
Severe storms are also a concern for these areas. A level 2 of 5 “slight risk” for severe weather is up from Tallahassee, Florida, to Columbia, South Carolina, for severe storms from Isaias’ outer bands. Damaging winds and tornadoes are possible with these storms later Saturday.
The heaviest rain will be over the coastal Carolinas and southern Appalachia later Saturday, with light rain beginning to spread into Indiana and West Virginia.
More rain is expected to move through the mid-Atlantic Sunday morning and through the Northeast later in the afternoon.

At 2 a.m. ET, the National Hurricane Center declared Isaias a post-tropical cyclone -- a system that no longer possesses characteristics of a tropical system.
More than a foot of rain has fallen so far in parts of Georgia and Florida from Isaias, including 12.97 inches in Bellwood, Alabama, 12.47 inches in DeFuniak Springs, Florida, 11.63 inches in Graceville, Florida, and 10.01 inches in Elba, Alabama.
As of the latest update from the National Hurricane Center, Isaias is over southern Alabama with maximum sustained winds of 35 mph and is moving north at 14 mph.
Since Isaias has weakened to below tropical storm strength, all storm surge and tropical storm alerts have been discontinued. However, wind advisories remain up across much of the region for sustained winds of 20 to 30 mph with gusts up to 50 mph possible through Sunday morning.
