According to the National Hurricane Center, Michael has made landfall just ahead 1pm CDT as a Category 4 Hurricane with maximum sustained winds of 155mph. This is 2mph below Category 5 strength on the Saffir-Simpson Scale.
Michael is the first Category 4 storm to make landfall in this part of Florida recorded history (since 1851), and the second Category 4 storm to make a Florida landfall in two years (Irma, 2017). An extreme wind warning was issued by the National Weather Service in Tallahassee until later this afternoon. Storm surge up to 12 feet will be possible in the strongest parts of the storm on the coast. 7 feet had already been measured ahead of landfall.
In addition to devastating wind and storm surge, isolated rainfall totals of a foot or more will be possible in the heaviest rain bands.
Several inches are expected along and east of the center of circulation as the storm travels northeastward and eventually moves back into the ocean later this week, getting swept up by the jetstream.
