Southwestern Atlantic (AL94):
Showers and thunderstorms continue to show signs of organization in
association with a tropical wave located near Hispaniola, the
Turks and Caicos Islands, and eastern Cuba. An area of low pressure
is expected to form along the wave by tonight when it moves near the
southeast Bahamas. This low is expected to become a tropical
depression when it is in the vicinity of the central and northwest
Bahamas over the weekend, and then track northwestward or northward
over the southwestern Atlantic.
Regardless of development, heavy rains and gusty winds are ongoing
in the Dominican Republic, Haiti, and the Turks and Caicos Islands,
and are likely to spread across the Bahamas and eastern Cuba during
the next day or two. Interests in all of these areas should monitor
the progress of the system. While there remains considerable
uncertainty in the long-range track and intensity of the system,
there is a significant risk of wind, rainfall, and storm surge
impacts for a portion of the southeast U.S. coast early next week.
Interests in this area should also monitor the progress of the
system.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Imelda, located east of Bermuda.
Central Tropical Atlantic:
A tropical wave is expected to move off the coast of Africa over the
next day or two. Thereafter, this wave is forecast to interact with
another disturbance in the eastern tropical Atlantic, and some slow
development of the combined feature is possible as the system moves
westward to west-northwestward at 15 to 20 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
Southwestern Atlantic:
An area of low pressure may form along a remnant frontal boundary
near the northwestern Bahamas and southern Florida over the next
couple of days. Any additional development is expected to be slow
to occur as the system moves northwestward across the Florida
Peninsula and into the Gulf of America.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

For the North Atlantic...Caribbean Sea and the Gulf of America:
Southwestern Atlantic:
A weak area of low pressure has formed near the central Bahamas
along the remnants of a frontal boundary. This system is expected to
meander near Florida and the Bahamas for the next several days.
Strong upper-level winds are expected to prevent significant
development of the low, however the combination of the disturbance
with the broader remnant boundary are still expected to produce
heavy rainfall across portions of Florida and the Bahamas through
the weekend.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
Central Tropical Atlantic:
A tropical wave is expected to move off the coast of Africa today.
The wave is forecast to interact with another disturbance over the
eastern tropical Atlantic, and then move westward after that.
Environmental conditions are expected to become conducive for some
slow development of the system in a few days, and a tropical
depression could form near or east of the Lesser Antilles by the end
of next week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.

For the North Atlantic...Caribbean Sea and the Gulf of America:
Bahamas and Southern Florida:
A weak area of low pressure located near the northwestern Bahamas
continues to produce disorganized shower activity. This system is
expected to drift west-northwestward across the northwestern Bahamas
and toward southern Florida during the next day or two, however
development is not expected due to strong upper-level winds. Heavy
rainfall could lead to flash flooding across portions of the east
coast of Florida and the northwestern Bahamas during the next few
days.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...near 0 percent.
North-Central Gulf:
A weak area of low pressure has formed over the north-central Gulf
and is producing disorganized showers and thunderstorms off the
coasts of Louisiana, Mississippi, and Alabama. This system is
expected to move slowly northwestward during the next day or two,
reaching the coast of Texas by Monday. Development of this system
is not expected due to strong upper-level winds.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...near 0 percent.
Tropical Atlantic:
A tropical wave between the west coast of Africa and Cabo Verde
Islands is producing a broad area of disorganized showers and
thunderstorms. Gradual development of the wave is possible over
the next few days, and it could become a tropical depression by the
middle to latter part of next week while moving across the
central tropical Atlantic and approaching portions of the Leeward
Islands.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...50 percent.

Showers and thunderstorms are gradually becoming better organized in association with an area of low pressure located a little more than
1000 miles east of the Windward Islands. If these trends continue,

A trough of low pressure located over the Yucatan Peninsula is
producing a large area of disorganized showers and thunderstorms.
This system is expected to emerge over the Bay of Campeche later

of development, areas of heavy rain and gusty winds are likely
across portions of the Yucatan Peninsula, Belize, and southern
Mexico during the next couple of days.
