For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
- A non-tropical low pressure system located over the central Atlantic between Bermuda and the Azores is producing winds to gale force. Environmental conditions are forecast to be generally conducive for the low to acquire some subtropical or tropical characteristics, and this system could become a tropical or subtropical storm later today or early Wednesday while it moves slowly westward. Upper-level winds are expected to become unfavorable for further development by Wednesday evening.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.
- Showers and thunderstorms over the western Atlantic between the southeastern coast of the United States and Bermuda are associated with a broad, non-tropical area of low pressure. This system is forecast to move northward or northeastward and could acquire some subtropical characteristics off the east coast of the United States by the end of the week.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...30 percent.
- A trough of low pressure extending across the southern Florida peninsula and into the southwestern Atlantic is producing disorganized showers and thunderstorms. Some slight development of this system is possible today when it moves off the southeast U.S. coast and north of the Bahamas. The disturbance is forecast to merge with a low off the east coast of the United States by Wednesday, and no further development is anticipated after that time. Regardless of development, this system is expected to produce locally heavy rainfall over portions of the Florida peninsula during the next day or so.
* Formation chance through 48 hours...low...10 percent.
