Hurricane Helene is gaining strength and is expected to rapidly intensify as it approaches Florida on Thursday. The National Hurricane Center says the storm will bring "catastrophic" winds and storm surge to the northeastern Gulf coast.

Florida is bracing for “unsurvivable” storm surge from Hurricane Helene, a Category 4 storm. In the afternoon, Helene was accelerating toward Florida’s Big Bend, bringing tropical storm conditions across most of the state’s western coast.

According to the National Hurricane Center, the highest chance of tropical development over the next week is in the Caribbean Sea and Gulf of Mexico.
