TAMPA, FL (TIP): Fast and furious large-scale Hurricane Irma is sweeping towards Florida. If the storm reaches its full potential, it could be one of the worst hurricanes in the state’s history.

It’s not clear exactly where the storm will make landfall, but winds well in excess of 100 mph could batter numerous population centers along Florida’s west coast. And coastal waters could rise 10 to 15 feet above normally dry land, completely inundating homes, businesses, and roads.

Hurricane warnings cover much the Florida peninsula’s coastal areas. Hurricanes watches extended farther north into coastal Georgia and South Carolina. 5 million have been told to flee.
