Hurricane Helene made landfall in Florida's Big Bend region as a catastrophic Category 4 storm Thursday night, lashing the region with devastating winds and an "unsurvivable" storm surge. At least three deaths have been reported from Florida to Georgia.

Storm surge is a bigger killer than wind when a major hurricane hits shore. The areas in the path of Hurricane Helene are more susceptible to surge than other parts of Florida's coast.

Fast-moving Hurricane Helene was advancing Thursday across the Gulf of Mexico toward Florida, threatening an “unsurvivable” storm surge in northwestern parts of the state as well as damaging winds, rains and flash floods hundreds of miles inland across much of the southeastern U.
