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).
