MIAMI (CBSMiami) – Powerful Hurricane Michael continues gaining strength as it bears down on the Florida Panhandle.
At 11 p.m. the center of the Category 3 hurricane was about 220 miles south of Panama City.
Michael is moving toward the north near 12 mph.
A northward motion is expected through tonight, followed by a northeastward motion on Wednesday and Thursday.
On the forecast track, the center of Michael will move across the eastern Gulf of Mexico through tonight.
The center of Michael’s eye is then expected to move inland over the Florida Panhandle or Florida Big Bend area on Wednesday, and then move northeastward across the southeastern United States Wednesday night and Thursday, and move off the Mid-Atlantic coast away from the United States on Friday.
Data from a NOAA Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 125 mph with higher gusts.
Michael is now a strong category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale.
Some further strengthening is expected overnight and on Wednesday, and Michael is forecast to become a category 4 hurricane before it makes landfall in the Florida Panhandle or the Florida Big Bend area.
Weakening is expected after landfall as Michael moves across the southeastern United States.
Hurricane-force winds extend outward up to 45 miles from the center and tropical-storm-force winds extend outward up to 175 miles.
The minimum central pressure recently measured by the reconnaissance aircraft was 947 mb.
