A Hurricane Warning means that hurricane conditions are expected

36 hours before the anticipated first occurrence of tropical storm
force winds, conditions that make outside preparations difficult or
dangerous. Preparations to protect life and property should be
rushed to completion.

A Hurricane Watch means that hurricane conditions are possible
within the watch area, in this case within the next 36 to 48 hours.

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


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 AM EDT (0900 UTC), the center of Tropical Storm Joaquin was
located near latitude 25.4 North, longitude 72.5 West. Joaquin is
moving toward the west-southwest near 6 mph (9 km/h), and this
motion is expected to continue through tonight. A turn toward the
west and a decrease in forward speed are forecast on Thursday. On
the forecast track, the center of Joaquin is expected to move near
or over portions of the central Bahamas tonight and Thursday.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Strengthening is forecast during the next 48 hours, and
Joaquin is forecast to become a hurricane today. An Air Force
Reserve Hurricane Hunter aircraft is en route to investigate Joaquin
this morning.

Tropical storm force winds extend outward up to 125 miles (205 km)
from the center.

The estimated minimum central pressure is 988 mb (29.18 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected to reach the hurricane
warning area by midday Thursday. Winds are expected to first reach
tropical storm strength in the warning area tonight, making outside
preparations difficult or dangerous. Preparations to protect life
and property should be rushed to completion.

RAINFALL:  Joaquin is expected to produce 5 to 10 inches of rain
with isolated maximum amounts of 15 inches possible over San
Salvador and Rum Cay through Friday morning. Rainfall amounts of 3
to 5 inches are possible over the remainder of the central Bahamas
through Friday morning, with 2 to 4 inches expected over the
northwestern and southeastern Bahamas.

SURF:  Swells generated by Joaquin will affect portions of the
Bahamas during the next few days, and will begin to affect portions
of the east coast of Florida and the southeast coast of the United
States by Friday. These swells are likely to cause life-threatening
surf and rip current conditions. Please consult products from your
local weather office.
