Stream FOX 35 News

Hurricane Helene is now an "extremely dangerous" Category 4 hurricane, as it moves up Florida's Gulf Coast towards the state's Big Bend region.

It's expected to make landfall Thursday night somewhere over Florida's Big Bend region, though officials have said nearly the entire state will experience dangerous, life-threatening impacts, including "catastrophic" storm surge, dangerous winds, heavy rain, and an increased risk of tornadoes.

In a surprise 6:20 p.m. advisory, the National Hurricane Center said NOAA Hurricane Hunters found that Helene had maximum sustained winds of 130 mph, making it an extremely dangerous Category 4 hurricane.

In its 5 p.m. update, Helene had sustained winds of 125 mph, making it a Cat. 3 hurricane and 5 mph shy of being a Cat. 4 at the time.

Storm watches and warnings

Nearly all of Florida's 67 counties – aside from a handful – are under some sort of tropical advisory, watch, or warning. Those warnings even extend to parts of eastern Alabama, nearly all of Georgia, and parts of South Carolina.

Much of north, north-central, and north-western Florida are under a tornado watch throughout the night, as Helene barrels towards the Big Bend area.

When will the worst impacts from Hurricane Helene be felt in Central Florida?

Central Florida – Orlando and the surrounding cities – began to feel the impacts of Hurricane Helene on Wednesday. The weather will rapidly deteriorate on Thursday afternoon, including tropical storm-force winds, wind gusts, heavy rain, and the potential for tornado warnings.
