DISCUSSION AND OUTLOOK
At 200 AM EDT (0600 UTC), the center of Tropical Storm Michael was
located near latitude 37.3 North, longitude 75.1 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 away from the coast of the United
States during the next few hours and then begin to race
east-northeastward across the northwestern Atlantic Ocean.
Surface observations indicate that maximum sustained winds have
increased near 60 mph (95 km/h) with higher gusts. Michael is
expected to continue to strengthen while becoming a post-tropical
low during the next few hours.
Tropical-storm-force winds extend outward up to 275 miles (445 km),
primarily over water to the southeast of the center. The National
Ocean Service station on the York River recently reported sustained
winds of 62 mph (99 km/h) and a wind gust of 83 mph (133 km/h) at an
elevation of 48 ft (15 m), while the Norfolk Naval Air Station
reported sustained winds of 54 mph (87 km/h) and a wind gust of
75 mph (120 km/h). Also, a Weatherflow station on the Chesapeake
Light Tower recently reported sustained winds of 81 mph (130 km/h)
and a wind gust of 96 mph (154 km/h) at an elevation of 135 ft
The estimated minimum central pressure is 985 mb (29.09 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
extreme eastern North Carolina, including the Outer Banks.
Gale- to storm-force winds are occurring over portions of
southeastern Virginia, extreme northeastern North Carolina, and the
Delmarva Peninsula, and these conditions will continue for the next
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
Rainfall totals of 1 to 3 inches are expected across the coastal
northern Mid-Atlantic and southern New England.
