Hurricane Debby is expected to slam into the Big Bend region of Florida's Gulf Coast around midday Monday before slowly crossing the state, causing potentially dangerous storm surges and catastrophic flooding, the National Hurricane Center (NHC) said. By 11:00 p.m. EDT (0300 GMT) on Sunday, the hurricane had sustained winds of 75 mph (120 km/h), growing from a slow-moving tropical storm that gained strength from warm Gulf waters. It will probably only get stronger.
