For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. Northwestern Atlantic (Post-Tropical Cyclone Tammy):
A strong extratropical cyclone (formerly Tammy) associated with an occluded front is located a few hundred miles east of Bermuda. This low is forecast to become separated from the front soon, and conditions appear favorable for the system to redevelop into a tropical storm later today or Saturday. Regardless of tropical redevelopment, the system is likely to bring gusty winds to Bermuda during the next day or so, and a gale warning is in effect for the island. Interests on Bermuda should monitor the progress of this system.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.
2. Western Caribbean Sea:
A broad area of low pressure is forecast to develop over the southwestern Caribbean Sea during the next few days. Environmental conditions could support some slow development of this system early next week while it moves generally northward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.
