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-northeast of
Puerto Rico, and on Tropical Depression Rose, located about 1000
miles west-northwest of the Cabo Verde Islands.
1. Showers and thunderstorms continue to become better organized in
association with a tropical wave located several hundred miles
southwest of the Cabo Verde Islands. Environmental conditions are
expected to remain conducive for additional development, and a
tropical depression is expected to form within a day or two while
the system moves westward at 10 to 15 mph across the eastern and
central tropical Atlantic Ocean. 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...high...90 percent.
* Formation chance through 5 days...high...90 percent.
2. A gale-force, non-tropical low pressure system, the remnants of
Odette, is located a little less than 500 miles west-northwest of
the westernmost Azores. This low could acquire some subtropical
characteristics over marginally warm waters during the next few days
while it makes a counter-clockwise loop over the north-central
Atlantic Ocean. However, by the weekend, this system is expected to
move into an environment of strong upper-level winds. 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...30 percent.
* Formation chance through 5 days...medium...50 percent.
