000 ABNT20 KNHC 291145 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Fri Sep 29 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Maria, located over the western Atlantic Ocean a few hundred miles south of Halifax, Nova Scotia, and on Hurricane Lee, located over the north Atlantic Ocean several hundred miles south-southeast of Newfoundland. A broad trough of low pressure interacting with an upper-level low is producing a large but disorganized area of cloudiness and showers. This activity extends from the northwestern Caribbean Sea northward across western Cuba to the southern Florida peninsula. This trough has moved slowly westward since yesterday, and a weak low is now likely to form from this system near the west coast of Florida during the weekend. Environmental conditions appear to be conducive for some development of the low before the upper-level winds become less favorable early next week. Regardless of development, this system is likely to produce locally heavy rainfall over portions of central and western Cuba, the Florida Keys, the Florida peninsula during the next several days. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 5 days...medium...40 percent. A tropical wave is producing cloudiness and showers over the northeastern Caribbean Sea and the adjacent Atlantic waters. Although there are no signs of organization and surface pressures are not falling at this time, conditions could become a little more favorable for some development next week while the system moves toward the west-northwest. This system is expected to bring locally heavy rains over the northern Leeward Islands, including Puerto Rico and the U.S. Virgin Islands. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...20 percent. $$ Forecaster Avila
