Hurricane Helene's landfall is expected in the next few hours -- likely between 10 p.m. to 11 p.m. -- as a major Category 4 in Florida's Big Bend region.
As of 8 p.m. ET, hurricane-force gusts extend outward 60 miles from the center of the storm and tropical storm-force gusts extend outward 310 miles from the center.
Some additional strengthening is possible before the center reaches Florida's coast on Thursday.
Although weakening is expected after Helene moves inland, the storm is moving fast and it is powerful. Damaging wind gusts will penetrate well inland across the Southeastern states.
Ahead of Helene's landfall, there was a 76 mph gust reported in St. Pete.
