Warm water is like jet fuel for hurricanes, and a combination of balmy conditions in the Gulf of Mexico, a lack of disturbance from wind shear and rapid intensification near the coast turned Michael into a historic storm, according to hurricane experts.
With a low barometric pressure recorded at 919 millibars, the measure of a hurricane's force, Michael ranked as the third-strongest storm on record to make landfall in the continental United States.
Florida has issued mandatory or voluntary evacuation orders in at least 22 counties on the Gulf Coast, with Governor Rick Scott urging people yesterday to get out of the way of the "monstrous storm", CNN reported.

It appeared to be so powerful that it was expected to remain a hurricane as it moved into Alabama and Georgia early Thursday.
