Interests in the Cabo Verde Islands should monitor the progress of this system as gusty winds and locally heavy rainfall are likely there Monday night and Tuesday. A Tropical Storm Watch or Warning could be required for the islands by early Monday. * Formation chance through 48 hours...high...90 percent. * Formation chance through 5 days...high...90 percent. A tropical wave located over the central Caribbean Sea south of Jamaica and extending northward across the island is producing limited shower and thunderstorm activity. Upper-level winds are forecast to remain unfavorable for development for the next several days while the system moves westward, and tropical cyclone formation is not expected. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...near 0 percent. A trough of low pressure located just to the southeast of Bermuda is producing disorganized cloudiness and showers. Some slow development of this system is possible during the next several days while it moves west-northwestward. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...30 percent. A new tropical wave is forecast to emerge off the west coast of Africa by the middle to latter part of this week. Some gradual development will be possible thereafter while the system moves generally westward. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...20 percent. $$ Forecaster Stewart
