DISCUSSION AND 48-HOUR OUTLOOK
At 1100 AM EDT (1500 UTC), the center of Hurricane Maria was located
near latitude 31.2 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 Tuesday night. On
the forecast track, the center of Maria will move well east of the
southeast coast of the United States during the next day or so.
Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds are near 80 mph (130 km/h)
with higher gusts. Gradual weakening is forecast during the next
couple of days and Maria is forecast to become a tropical storm
Maria is a large hurricane. Hurricane-force winds extend outward up
to 90 miles (150 km) primarily to the east of center and tropical-
storm-force winds extend outward up to 230 miles (370 km).
The latest minimum central pressure reported by reconnaissance
aircraft is 963 mb (28.44 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected within the warning
area beginning Tuesday. Tropical storm conditions are possible
within the watch area beginning Tuesday.
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 rainfall accumulations
of 1 to 2 inches over the Outer Banks of North Carolina through
SURF: Swells generated by Maria are affecting portions of the coast
of the southeastern United States and Bermuda and will be increasing
along the Mid-Atlantic and southern New England coasts today.
Swells also continue to affect Puerto Rico, the northern coast of
Hispaniola, 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.
