OTHER SYSTEMS:
1. Southwestern Caribbean Sea: Disorganized showers and thunderstorms over the southwestern Caribbean Sea are associated with a broad area of low pressure. Gradual development of this system is expected, and a tropical
depression is likely to form within the next few days while the system moves generally northward to northwestward over the central and western Caribbean Sea. Regardless of development, locally heavy rains are possible over portions of the adjacent land areas of the western Caribbean, including Jamaica, Hispaniola, and Cuba. Interests in the western Caribbean Sea should monitor the progress of this system.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...high...80 percent.
2. Near the Greater Antilles: A large area of disorganized showers and thunderstorms, and gusty winds extending from near Puerto Rico and Hispaniola northeastward for a few hundred miles are associated with a trough of low
pressure. Slow development of this system is possible during the next couple of days while it moves west-northwestward near the Greater Antilles. By early next week, this system is expected to be absorbed into the low pressure area over the Caribbean Sea. Regardless of development, locally heavy rains are possible during the next few days across the northern Leeward Islands, Puerto Rico, Hispaniola, eastern Cuba and the southeastern Bahamas. For more
information on this system, including gale warnings, see High Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
