DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Michael was located near latitude 37.1 North, longitude 76.1 West. Michael is moving toward the northeast near 25 mph (41 km/h). An east- northeastward motion with a significant increase in forward speed is expected during the next couple of days. On the forecast track, the center of Michael will move off the coast of Virginia within the next hour or two and then begin to race east-northeastward across the northwestern Atlantic Ocean. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Michael is expected to become a post-tropical low overnight and then intensity over the western Atlantic on Friday. Tropical-storm-force winds extend outward up to 275 miles (445 km), primarily over water to the southeast of the center. The estimated minimum central pressure is 988 mb (29.18 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.

RAINFALL: Michael is expected to produce total rain accumulations of 3 to 5 inches across southeast Virginia, southeast Maryland, Delaware, and southern New Jersey. Isolated maximum totals of 7 inches are possible. This rainfall could lead to life-threatening flash floods.
