At 100 PM CDT (1800 UTC), the eye of Hurricane Michael was located
near latitude 30.0 North, longitude 85.5 West. Michael is moving
toward the north-northeast near 14 mph (22 km/h). A turn toward the
northeast is expected this afternoon or tonight. A motion toward
the northeast at a faster forward speed is forecast on Thursday
through Friday night. On the forecast track, the core of Michael
will move inland across the Florida Panhandle this afternoon, and
across southeastern Alabama and southwestern Georgia tonight.
Michael will move northeastward across the southeastern United
States through Thursday night, and then move off the Mid-Atlantic
coast away from the United States on Friday.

aircraft indicate that maximum sustained winds have increased to
near 155 mph (250 km/h) with higher gusts. Michael is an extremely

occurs at the time of high tide...
Tyndall Air Force Base FL to Aucilla River FL...9-14 ft
Okaloosa/Walton County Line FL to Tyndall Air Force Base FL...6-9 ft
