Michael now "extremely dangerous" Category 4 hurricane

Hurricane Michael strengthened into a fierce Category 4 storm early Wednesday, with maximum sustained winds of 130 mph, the National Hurricane Center said.

Forecasters said Michael could produce a life-threatening storm surge as high as 13 feet in some areas and as much as a foot of rain in some spots.

As of 2 a.m., Michael was some 180 miles south-southwest of Panama City, Florida and about 170 miles southwest of Apalachicola, Florida, moving due north at a steady clip of 12 mph.

"On its forecast track," the center said, "the center of Michael will move across the northeastern Gulf of Mexico this morning. The center of Michael's eye is then expected to move inland over the Florida Panhandle or Florida Big Bend area later today, move northeastward across the southeastern United States tonight and Thursday, and then move off the Mid-Atlantic coast away from the United States on Friday."
