DISCUSSION AND 48-HOUR OUTLOOK
At 200 AM EDT (0600 UTC), the center of Hurricane Maria was located
near latitude 30.2 North, longitude 73.0 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. On the
forecast track, the core 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 have decreased to near 85 mph
(135 km/h) with higher gusts. Additional slow weakening is forecast
during the next 48 hours.
Maria is a large hurricane. Hurricane-force winds extend outward
up to 60 miles (95 km) from the center and tropical-storm-force
winds extend outward up to 230 miles (370 km).
The minimum central pressure recently reported by the Hurricane
Hunter aircraft is 954 mb (28.17 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are possible within the watch area
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.
SURF: Swells generated by Maria are increasing along portions of
the southeastern United States coast and Bermuda and will be
increasing along the Mid-Atlantic coast tonight and Monday. Swells
also continue to affect Puerto Rico, the Virgin Islands, 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.
