DISCUSSION AND 48-HOUR OUTLOOK
At 800 AM EDT (1200 UTC), the center of Tropical Storm Maria was
located near latitude 35.4 North, longitude 72.8 West. Maria is
moving toward the north near 5 mph (7 km/h). A turn toward the
north-northeast is expected later today, followed by an acceleration
toward the east-northeast on Thursday. On the forecast track,
Maria's center will begin to move slowly away from the coast of
North Carolina later today and tonight.
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Some gradual weakening is forecast during the next couple
Tropical-storm-force winds extend outward up to 230 miles (370 km)
from the center. An unoffical weather observing site near Oregon
Inlet, North Carolina, recently reported a sustained wind of 43 mph
(69 km/h) with a gust to 49 mph (80 km/h).
The estimated minimum central pressure is 978 mb (28.88 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected within the warning
area through today.
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 is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide...
Cape Lookout to Duck including the sound side of the Outer
Banks...2 to 4 ft
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.
RAINFALL: Maria is expected to produce additional rain
accumulations of less than 1 inch over the Outer Banks of North
Carolina and far southeast Virginia through Wednesday night.
SURF: Large swells generated by Maria are affecting much of the
east coast of the United States, Atlantic Canada, Bermuda, the
Bahamas, and the Turks and Caicos Islands. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office for more
