NHC Forecasting A Landfalling CAT 3 Hurricane Tomorrow

#13,579

With winds now at a solid 110 MPH - Hurricane Michael is on the cusp of becoming a CAT 3 storm - and with another 24 hours of warm water to cross, is expected to intensify further before landfall. 
The forecast track has remained constant for the past few model runs, putting landfall in the panhandle tomorrow afternoon.   The forecast cone (above) does not - however - show the full extent of this storm's likely impact, or damage. 

From the 11am discussion by the National Hurricane Center. 
Michael is moving between north-northwest and north at about 10 kt. The track forecast reasoning is the same as the past several advisories, as Michael should move generally northward through early Wednesday between a ridge over the western Atlantic and a deep-layer trough over the central United States. As the trough moves eastward it will cause Michael to turn northeastward on Wednesday.
The hurricane should then continue northeastward and accelerate as it becomes embedded in the mid-latitude westerlies. The track guidance is in very good agreement through the first 36-48 hours, with some differences in forward speed thereafter. The GFS and ECMWF have trended slower after landfall, and the new NHC track has been adjusted accordingly.

It would not surprise me to see hurricane conditions extend into southern Alabama and Georgia, and residents there and across much of the Florida panhandle should be prepared to deal with prolonged power outages.

Storm surge, particularly to the right (east) of where the eye comes ashore, is likely to be severe, with 9+ feet of water over the land in some places.  If you live in an evacuation zone, now is the time to leave.
