DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 PM EDT (2100 UTC), the center of Hurricane Maria was located
near latitude 31.7 North, longitude 73.1 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.
A turn toward the north-northeast is expected on Wednesday. On the
forecast track, the center of Maria will pass east of the coast of
North Carolina during the next couple of days.
Reports from a NOAA reconnaissance 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 Tuesday night or
Wednesday.
Maria is a large hurricane. Hurricane-force winds extend outward up
to 105 miles (165 km) from the center and tropical-storm-force winds
extend outward up to 205 miles (335 km). NOAA buoy 41002, located
about 100 miles west-northwest of Maria's center, recently reported
sustained winds of 44 mph (70 km/h) and a gust to 56 mph (91 km/h).
The minimum central pressure estimated from reconnaissance aircraft
observations is 965 mb (28.50 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected within the warning
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
Wednesday.
SURF: Large swells generated by Maria are affecting much of the
east coast of the United States from Florida through southern New
England. These swells are also affecting Bermuda, 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.
