DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Tropical Storm Michael was
located near latitude 36.5 North, longitude 77.8 West.  Michael is
moving toward the northeast near 24 mph (39 km/h), and this motion
is expected to continue with an increase in forward speed through
tonight. A turn toward the east-northeast at an even faster forward
speed is expected on Friday and Saturday. On the forecast track, the
center of Michael will cross into southeastern Virginia during the
next couple of hours and then move into the western Atlantic Ocean
overnight.

Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Michael is forecast to intensify as it becomes a
post-tropical low over the Atlantic late tonight and Friday.

Tropical-storm-force winds extend outward up to 230 miles (370 km),
primarily over water to the southeast of the center.  A sustained
wind of 45 mph (72 km/h) and a gust to 67 mph (108 km/h) was
recently reported at Cherry Point Marine Corps Air Station in North
Carolina.

The estimated minimum central pressure based on recent surface
observations is 989 mb (29.20 inches).


HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  The combination of a dangerous storm surge and the
tide will 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 tide...

Sound side of the North Carolina Outer Banks from Ocracoke Inlet
to Duck...2-4 ft

WIND:  Tropical storm conditions are occurring over portions of
northeastern South Carolina and central and eastern North Carolina.
Damaging tropical-storm-force wind gusts will spread from central
North Carolina and southern Virginia across northeastern North
Carolina and eastern Virginia during the next several hours.

Gale- to storm-force winds are expected over portions of
southeastern Virginia, extreme northeastern North Carolina, and the
Delmarva Peninsula late tonight and Friday morning when Michael
becomes post-tropical off the Mid-Atlantic coast.

RAINFALL:  Michael is expected to produce total rain accumulations
of 4 to 7 inches from north-central North Carolina, into south-
central to southeast Virginia, including the southern Delmarva
Peninsula. Isolated maximum totals of 9 inches are possible in North
Carolina and Virginia.  This rainfall could lead to life-threatening
flash floods.

Rainfall totals of 1 to 3 inches expected across the coastal
northern Mid-Atlantic and southern New England.

TORNADOES:  A few tornadoes are possible through this evening from
northeastern North Carolina across southeast Virginia into the
Delmarva Peninsula.
