For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Central Subtropical Atlantic (AL90):
Satellite images indicate that disorganized showers and
thunderstorms are displaced to the east of an area of low pressure
located about 600 miles east of Bermuda. Environmental conditions
are still marginally favorable for further development, and an
increase in thunderstorm activity could result in the formation of a short-lived tropical depression today. By Tuesday, this system is
expected to encounter less favorable environmental conditions,
ending its opportunity for development. The system is forecast to
move northeastward around 10 mph, remaining over the open central
Atlantic.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Special outlook issued to update AL90 formation chances
Central Subtropical Atlantic (AL90):
Satellite images indicate that shower and thunderstorm activity
has become better organized in association with a small gale-force
low-pressure system located about 900 miles east-northeast of
Bermuda. This system will likely become a short-lived tropical
storm later today before more hostile environmental conditions end
its opportunity for development by this evening. The low is
forecast to move northeastward at around 15 to 20 mph while
remaining over the open central Atlantic. For additional
information, including gale warnings, please see High Seas
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.

Bay of Campeche:
An area of disorganized showers and thunderstorms over the
northwestern Caribbean sea and the adjacent land areas is expected
to move west-northwestward into the Bay of Campeche Saturday or
Saturday night, where an area of low pressure could form.
Subsequent development is possible on Sunday or Monday if the system
remains offshore of the coast of Mexico. Regardless of development,
locally heavy rains are possible over portions of Belize, Guatemala,
and southeastern Mexico during the next few days.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Bay of Campeche (AL91):
An area of low pressure located in the eastern Bay of Campeche near
the Mexican coastline continues to produce a broad region of
disorganized shower and thunderstorm activity over the Yucatan
Peninsula and adjacent waters. Additional development is possible
today and Sunday as the low moves generally west-northwestward, and
a tropical depression could form during this period while the system
remains over the waters of the Bay of Campeche. By Monday, this
system should move inland over eastern Mexico, ending its chances of development. Regardless of tropical cyclone formation, locally heavy
rains are possible over portions of Belize, Guatemala, and
southeastern Mexico during the next few days. An Air Force Reserve
Hurricane Hunter aircraft is scheduled to investigate the system
later today, if necessary.
* Formation chance through 48 hours...medium...50 percent.
