DISCUSSION AND OUTLOOK
———————-
At 200 PM EDT (1800 UTC), the center of Tropical Storm Michael was
located near latitude 35.7 North, longitude 80.0 West. Michael is
moving toward the northeast near 23 mph (37 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 continue to move across central and
eastern North Carolina today, move across southeastern Virginia this
evening, and move into the western Atlantic Ocean tonight.
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts, primarily over water south and east of the center. Little
change in strength is expected today, with the strongest winds
primarily spreading northward along the coast of the Carolinas.
Michael is forecast to intensify as it becomes a post-tropical low
over the Atlantic late tonight.
Tropical-storm-force winds extend outward up to 185 miles (295 km),
mainly to the south and east of the center. A wind gust of 55 mph
(89 km/h) was recently reported at North Myrtle Beach, South
Carolina. A wind gust to 49 mph (80 km/h) has been reported at
Wilmington, North Carolina.
The estimated minimum central pressure based on surface observations
is 991 mb (29.26 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 will spread northward over central
and eastern North Carolina through this evening. Tropical storm
force wind gusts are expected across portions of North Carolina and
Virginia this afternoon and tonight.
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 northern South Carolina, west-central to
northwestern North Carolina, and 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 Central
Appalachians into the Mid-Atlantic and southern New England.
TORNADOES: Tornadoes are possible through this evening across
central and eastern North Carolina and southeast Virginia.
