The NHC reported the storm was about 180 miles south-southwest of Panama City, FL. Producing heavy rainfall and strong winds, Michael is moving north at 12 mph, and it’s packing maximum-sustained winds of 130 mph.

“Water levels will rise well in advance of the center of Michael, and residents within the storm surge warning area should finish preparations to protect life and property today,” the NHC said Tuesday afternoon.
After making landfall, Michael is expected to cut a path across the Southeast, including North and South Carolina, states that are still recovering from Hurricane Florence in September. The storm is expected to hit parts of Alabama and Georgia before heading northward to Virginia and Maryland.
Heavy rainfall could produce life-threatening flash flooding from the Florida Panhandle and Big Bend region, into parts of Georgia, the Carolinas and southeast Virginia.
