Surface observations and coastal radar data indicate that an area of low pressure has developed near the northeastern coast of the Florida Peninsula between Daytona Beach and St. Augustine, and that winds to near gale-force are occurring to the north of the center. Additional development into a tropical cyclone appears unlikely due to unfavorable upper-level winds. However, gusty winds and locally heavy rains are likely over portions of northeastern Florida and southeastern Georgia tonight and Sunday. Please see statements from local National Weather Service forecast offices for additional information. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...low...20 percent. 2. A tropical wave interacting with an upper-level low is producing a large but disorganized area of cloudiness and showers extending from the eastern Caribbean Sea northward across the Leeward Islands, Virgin islands, and Puerto Rico to the nearby Atlantic waters. Environmental conditions are not favorable for development and tropical cyclone formation is not forecast. This system is expected to move west-northwestward to westward at 10 to 15 mph during the next few days bringing locally heavy rainfall over portions of the northern Leeward Islands, the Virgin Islands and the Greater Antilles during the next several days. A Flash Flood Watch in effect for Puerto Rico and the U.S. Virgin Islands through late Sunday night. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...near 0 percent.
