As Hurricane Helene approaches Florida's Big Bend coast, the National Weather Service (NWS) has issued a dire warning, calling the expected storm surge "unsurvivable." The rapidly intensifying storm is forecast to make landfall on Thursday evening as a Category 3 or stronger hurricane and evacuations have been ordered for several Florida counties.

In a special update from the National Hurricane Center, Helene made landfall just east of the mouth of the Aucilla River. This is about 10 miles west-southwest of Perry, Florida. Based on data from Air Force reconnaissance aircraft, the maximum sustained winds are estimated to be 140 mph.

Long before its landfall late Thursday, Hurricane Helene and its intense wind and rain were already threatening millions of people in four states.
