and on Tropical Depression Twelve, located over the eastern
tropical Atlantic Ocean.

Western Caribbean Sea and Gulf of Mexico:
A large and disorganized area of low pressure located over the
western and southwestern Caribbean Sea is producing some shower and

conducive for gradual development, and a tropical depression could
form in a few days while the system is over the southern Gulf of
Mexico or northwestern Caribbean Sea.  While interests in the
northwestern Caribbean Sea and along the U.S. Gulf Coast should
continue to monitor the progress of this system, the timetable for
potential development has shifted later toward late week or this
weekend.

* Formation chance through 7 days...medium...40 percent.

Eastern Tropical Atlantic:
Showers and thunderstorms have increased in association with a
tropical wave located a few hundred miles south of the Cabo Verde
Islands.  Upper-level winds are forecast to become more conducive
for gradual development, and a tropical depression is likely to form
in a few days while it moves slowly westward over the eastern
tropical Atlantic.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...80 percent.
