WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

The meteorological service of Antigua and Barbuda has issued a
Tropical Storm Watch for St. Kitts and Nevis.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Hurricane Watch is in effect for...
* Guadeloupe
* Martinique
* Dominica

A Tropical Storm Watch is in effect for...
* Antigua
* Montserrat
* St. Kitts and Nevis

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.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere in the Leeward Islands should monitor the
progress of Isaac as additional watches could be issued this
afternoon or evening.

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


DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Tropical Storm Isaac was
located with high-resolution GOES-16 visible satellite data near
latitude 14.6 North, longitude 50.4 West. Isaac is moving toward the
west near 16 mph (26 km/h), and this motion is expected to continue
for the next few days. On the forecast track Isaac is anticipated
to move near or over the central Lesser Antilles on Thursday and
move into the eastern Caribbean Sea Thursday night.

Maximum sustained winds remain near 70 mph (110 km/h) with higher
gusts. Isaac is expected to be near hurricane strength when it
moves through the central Lesser Antilles, with some weakening
forecast afterward on Friday.

Tropical-storm-force winds extend outward up to 105 miles (165 km)
from the center.

The estimated minimum central pressure is 996 mb (29.42 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Isaac is expected to produce total rainfall accumulations
of 3 to 5 inches with isolated amounts near 10 inches across the
southern Leeward Islands late this week, with 1 to 2 inches
anticipated across portions of the Windward Islands.

STORM SURGE: A storm surge of 2 to 4 feet above normal tide levels
is possible near and to the north of where the center moves through
the Lesser Antilles. Near the coast, the surge will be accompanied
by large and destructive waves.

WIND: Hurricane conditions are possible within the hurricane watch
area by Thursday morning, with tropical storm conditions possible
early Thursday in both the hurricane and tropical storm watch areas.

SURF: Swells generated by Isaac will begin to affect portions
of the Lesser Antilles on Wednesday afternoon. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
