CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Hurricane Watch is in effect for...
* Antigua, Barbuda, Anguilla, Montserrat, St. Kitts, and Nevis
* Saba, St. Eustatius, and Sint Maarten
* Saint Martin and Saint Barthelemy

A Hurricane Watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

Interests in the remainder of the Leeward Islands, the British and
U.S. Virgin Islands, and Puerto Rico should monitor the progress of
Irma. Additional hurricane and tropical storm watches and
warnings will likely be required for portions of this area later
today.

For storm information specific to your area, please monitor products
issued by your national meteorological service.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 200 AM AST (0600 UTC), the center of Hurricane Irma was located
near latitude 17.0 North, longitude 51.5 West. Irma is moving
toward the west-southwest near 14 mph (22 km/h). A west-
southwestward to westward motion is expected through tonight. On
the forecast track, the center of Irma is expected to approach the
northern Leeward Islands late Tuesday.

Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Irma is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some strengthening is forecast during the
next 48 hours.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center, and tropical-storm-force winds extend outward up to 140
miles (220 km).

The estimated minimum central pressure is 961 mb (28.38 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are possible within the watch area by
Tuesday night, with tropical storm conditions possible by late
Tuesday.

SURF: Swells generated by Irma will begin affecting the northern
Leeward Islands today. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
