Although some gradual development of this system is possible during the next day or so, the chance for tropical cyclone formation should increase after the wave reaches the western Caribbean Sea in a couple of days. This disturbance is expected to cause locally heavy rains and gusty winds over portions of the Lesser Antilles, the Virgin Islands, and Puerto Rico today and tonight. These conditions should spread westward across the central Caribbean Sea and reach Hispaniola by Monday and Jamaica and Cuba by Tuesday. Interests in these areas and elsewhere in the Caribbean Sea should continue to monitor the progress of this system. For additional information on this system, see High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...medium...40 percent * Formation chance through 5 days...high...70 percent && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and on the Web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml. $$ Forecaster Kimberlain
