HAZARDS AFFECTING LAND
STORM SURGE: Water levels are beginning to recede in some
locations, however, the combination of a dangerous storm surge
and the tide will continue to cause normally dry areas near the
coast to be flooded by rising waters moving inland from the
shoreline. The water has the potential to reach the following
heights above ground if peak surge occurs at the time of high
Panama City FL to Keaton Beach FL...3-5 ft
Sound side of the North Carolina Outer Banks from Ocracoke Inlet to

central and southeastern Georgia, and will spread across portions
of eastern Georgia and southern South Carolina this morning.
Tropical storm conditions are expected to spread northward within
the warning area along the southeast U.S. coast beginning this
morning through Friday.
Gale- to storm-force winds are expected over portions of
southeastern Virginia, extreme northeastern North Carolina, and the
Delmarva Peninsula as Michael becomes post-tropical off the
Mid-Atlantic coast late tonight or Friday.
RAINFALL: Michael is expected to produce the following rainfall
amounts into Friday...
Georgia, the Carolinas, and into Virginia...3 to 6 inches, with
isolated maximum amounts of 8 inches. This rainfall could lead to
life-threatening flash floods.
Florida...an additional inch of rain is possible as the tropical
storm moves away from the state eastern Mid-Atlantic, southern New
England coast...1 to 3 inches.
TORNADOES: Isolated tornadoes remain possible today from Georgia
into the Carolinas.
SURF: Swells generated by Michael will affect the coasts of the
eastern, northern, and western Gulf of Mexico through this morning.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
