The eye of the hurricane, the release added, is expected to move inland over Florida on Wednesday before heading northeastward and possibly moving off the US Mid-Atlantic coast and away from the United States on Friday.
Earlier in the day the NHC said the storm had intensified to a category 2. Florida authorities said they expected Michael to hit the state as a category 3. Michael, which emerged in the Mexican Gulf, hit Honduras, Nicaragua and El Salvador on Monday and has reportedly claimed the lives of at least 13 people.
