For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. Northwestern Gulf of Mexico (AL90):
Showers and thunderstorms associated with a low pressure system and
weak frontal boundary over the northwestern Gulf of Mexico remain
disorganized. Upper-level winds are expected to remain unfavorable
for significant development of this system while it meanders over
the northwestern Gulf and eventually merges with another approaching
frontal system later today or on Saturday. Although tropical
cyclone development is unlikely, heavy rainfall is expected to
continue across portions of the northern Gulf Coast during the next
day or so. Additional information on this system can be found in
products issued by your local National Weather Service Forecast
Office and High Seas Forecasts issued by the National Weather
Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
2. Northwestern Atlantic (AL99):
Satellite images indicate that a gale-force low pressure system
located several hundred miles east of the U.S. Mid-Atlantic coast
is producing a large area of showers and thunderstorms that are
increasingly taking on a non-tropical structure. The low is
forecast to move north-northeastward at 15 to 20 mph offshore the
northeastern United States, reaching colder waters by this evening
and overnight, and its opportunity to acquire subtropical
characteristics appears to be decreasing. Additional information
on this system, including gale warnings, can be found in High Seas
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.
3. Northwestern Caribbean Sea and Southwestern Gulf of Mexico:
A tropical wave located near the coast of Belize and the Yucatan
Peninsula of Mexico continues to produce disorganized showers and
thunderstorms. The wave is forecast to move across Central
America and southeastern Mexico today and tonight, and some slow
development is possible over the weekend after the system emerges
over the southwestern Gulf of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
4. Eastern and Central Tropical Atlantic:
An elongated trough of low pressure over the eastern tropical
Atlantic is producing minimal shower and thunderstorm activity.
Development, if any, should be slow to occur while the disturbance
meanders through the early part of next week and then begins to
move west-northwestward across the central tropical Atlantic during
the middle to latter part of next week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...10 percent.
