For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Tropical
Depression Peter, located a few hundred miles north of Puerto Rico,
and on Tropical Depression Rose, located about 1000 miles
west-northwest of the Cabo Verde Islands.
1. Showers and thunderstorms remain well organized in association with
a tropical wave located several hundred miles southwest of the Cabo
Verde Islands. In addition, recent satellite wind data indicates
that the circulation is gradually becoming better defined. If these
trends continue, a tropical depression could form as soon as this
afternoon or evening. This system should move westward at 10 to 15
mph across the eastern and central tropical Atlantic Ocean.
Additional information on this system, including gale warnings, can

* Formation chance through 5 days...high...near 100 percent.
2. A gale-force, non-tropical low pressure system, the remnants of
Odette, is located more than 500 miles west-northwest of the
westernmost Azores. This low is beginning to develop more
concentrated shower activity and could become a subtropical or
tropical cyclone as it moves slowly across marginally warm waters
over the north-central Atlantic Ocean during the next several days.
However, by the weekend, this system is expected to move south into
an environment of strong upper-level winds. Additional information
on this system, including gale warnings, can be found in High Seas
