DISCUSSION AND 48-HOUR OUTLOOK
At 800 AM EDT (1200 UTC), the center of Hurricane Maria was located
near latitude 33.3 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 tonight. 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.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Gradual weakening is forecast during the next couple of
days, and Maria is forecast to become a tropical storm within the
next day or so.
Maria remains 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 240 miles (390 km).
NOAA buoy 41025, located about 15 miles (25 km) southeast of Cape
Hatteras, North Carolina, recently reported a wind gust to 45 mph
The minimum central pressure recently reported by reconnaissance
aircraft is 970 mb (28.65 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected within the warning
area beginning later 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 total rain accumulations
of 1 to 2 inches over the Outer Banks of North Carolina through
SURF: Large swells generated by Maria are affecting most of the
east coast of the United States. 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
