DISCUSSION AND 48-HOUR OUTLOOK
At 200 PM AST (1800 UTC), the center of Hurricane Maria was located
by an Air Force Reserve Hurricane Hunter aircraft just offshore of
the northwestern coast of Puerto Rico near latitude 18.5 North,
longitude 66.9 West. Maria is moving toward the northwest near 12
mph (19 km/h), and this general motion with a gradual decrease in
forward speed is expected through early Friday. On the forecast
track, the center of Maria will move away from the northwestern
coast of Puerto Rico this afternoon. The center will then pass
offshore of the northeastern coast of the Dominican Republic tonight
and Thursday and then move near the Turks and Caicos Islands and
southeastern Bahamas Thursday night and Friday.
Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Maria is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Little change in strength is forecast during
the next 48 hours, and Maria is expected to remain a dangerous major
hurricane through Friday.
Hurricane-force winds extend outward up to 60 miles (95 km) from
the center, and tropical-storm-force winds extend outward up to 150
miles (240 km). A sustained wind of 45 mph (72 km/h) with a gust
to 77 mph (124 km/h) was recently reported at Mayaguez, Puerto
Rico. A sustained wind of 46 mph (74 km/h) with a gust to 76 mph
(122 km/h) was recently reported at Cabo Rojo, Puerto Rico.
The minimum central pressure based on the aircraft data is 961 mb
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are occurring over portions of Puerto
Rico, and tropical storm conditions are continuing over the
remainder of Puerto Rico and the Virgin Islands. Tropical storm
conditions are likely beginning in the warning areas in the
Dominican Republic, and hurricane conditions should start in the
hurricane warning area tonight. Tropical storm conditions are
expected to begin in the Turks and Caicos Islands and the
southeastern Bahamas Thursday morning, with hurricane conditions
starting Thursday evening.
Wind speeds atop and on the windward sides of hills and mountains
and on high-rise buildings could be much stronger than the near-
surface winds indicated in this advisory.
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...
Puerto Rico...6 to 9 ft
The deepest water will occur along the immediate coast near and to
the north and east of the landfall location, where the surge will be
accompanied by large and destructive waves. 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.
A dangerous storm surge accompanied by large and destructive waves
will raise water levels by as much as 4 to 6 feet above normal tide
levels in the hurricane warning area in the Dominican Republic, and
1 to 3 ft elsewhere along the northern coasts of the Dominican
Republic and Haiti.
A dangerous storm surge accompanied by large and destructive waves
will raise water levels by as much as 10 to 15 feet above normal
tide levels in the hurricane warning area near and to the north of
the center of Maria for both the Southeastern Bahamas and the Turks
and Caicos Islands.
RAINFALL: Maria is expected to produce the following rainfall
totals through Friday:
Puerto Rico...20 to 25 inches, isolated 35 inches
U.S. and British Virgin Islands...additional 5 to 10 inches,
isolated 15 inches
Northern and eastern Dominican Republic, Turks and Caicos and
southeast Bahamas...8 to 16 inches, isolated 20 inches
Northern Haiti...2 to 4 inches
Rainfall on these islands will cause life-threatening flash floods
TORNADOES: Several tornadoes are possible over Puerto Rico and the
U.S. Virgin Islands today.
SURF: Swells generated by Maria are affecting the Leeward Islands,
Puerto Rico, and the Virgin Islands. These swells will begin
affecting the northern coast of Hispaniola, the Turks and Caicos
Islands, and the Southeastern Bahamas during the next day or two.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
