located near latitude 34.6 North, longitude 72.9 West. Maria is
moving toward the north near 7 mph (11 km/h), and this general
motion with some decrease in forward speed is expected through
tonight. A turn toward the north-northeast is expected on
Wednesday, and a turn toward the east-northeast is anticipated on
Thursday. On the forecast track, the center of Maria will pass east
of the coast of North Carolina during the next day or so.
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Some slight weakening is forecast during the next day or
Maria is a large tropical storm. Tropical-storm-force winds extend
outward up to 230 miles (370 km) from the center. Okracoke Island

HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected within the warning
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 total rain accumulations
of 1 to 2 inches over the Outer Banks of North Carolina through
SURF: Large swells generated by Maria are affecting much of the
east coast of the United States. These swells are also affecting
Bermuda, the Turks and Caicos Islands, and the Bahamas. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office
for more information.
