DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1100 AM AST (1500 UTC), the disturbance was centered near
latitude 12.2 North, longitude 50.5 West. The system is moving
toward the west near 22 mph (35 km/h). A slower west-northwest
motion is expected during the next couple of days. On the forecast
track, the system is expected to approach the Leeward Islands on
Monday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Strengthening is expected during the next 48 hours. The
disturbance is forecast to become a tropical storm later today and
could be near hurricane strength when it approaches the Leeward
Islands.

Satellite images indicate that the disturbance has become better
organized, and it is expected to become a tropical cyclone later
today or tonight.
* Formation chance through 48 hours…high…near 100 percent
* Formation chance through 5 days…high…near 100 percent

The estimated minimum central pressure is 1008 mb (29.77 inches).

 

HAZARDS AFFECTING LAND
———————-
WIND: Hurricane conditions are possible within portions of Leeward
Islands by Monday night or Tuesday, with tropical storm conditions
possible on Monday.

RAINFALL: The system is expected to produce total rain
accumulations of 5 to 10 inches with isolated maximum amounts of 15
inches across portions of the central and southern Leeward Islands
through Tuesday night. These rains could cause life-threatening
flash floods and mudslides.

SURF: Swells generated by the system are expected to begin
affecting the Lesser Antilles by Sunday night. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

Weather models are very aggressive with developing this into a hurricane once it moves into the Northeast Caribbean and hurricane conditions are possible for the Northern Leeward Islands. There could also be risk to Puerto Rico and the Dominican Republic in the longer term later next week.

GFS MODEL SUNDAY 2PM

The GFS model suggests this system will strengthen rapidly through at least tomorrow and possibly beyond tomorrow. Conditions are quite favorable for strengthening to a hurricane in a hurry so this will be watched very closely. You can expect Maria to burst on the scene later today. Longer term a west northwest track is favored possibly toward the Bahamas late next week. Intensity models are also very aggressive and more models than not, make Maria a major hurricane. This one will need to be watched.
