Hurricane Helene, which is currently Category 1, formed from an area of low pressure in the Caribbean, having strengthened rapidly over the last few days. The hurricane is expected to be the "strongest hurricane to make landfall in the U.S. this season," possibly hitting Category 3 or 4 strength.

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.
