DISCUSSION AND OUTLOOK
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Michael was
located near latitude 34.7 North, longitude 80.8 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

speed are 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.
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 54 mph
(87 km/h) was recently reported at Folly Island, South Carolina.
Myrtle Beach, South Carolina, recently reported a wind gust of 47
mph (76 km/h).
The estimated minimum central pressure based on surface observations
is 990 mb (29.23 inches).
