000 ABNT20 KNHC 291727 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM 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 Atlantic Ocean several hundred miles south-southeast of Halifax, Nova Scotia, and on Tropical Storm Lee, located over the north Atlantic Ocean about a 1000 miles west-northwest of the Azores. A broad trough of low pressure interacting with an upper-level low is producing a large but disorganized area of cloudiness and showers extending from the northwestern Caribbean Sea northward through the southern Florida peninsula. Environmental conditions appear to be marginally conducive for some development and a low pressure system could form near Florida or over the eastern Gulf of Mexico before the upper-level winds become unfavorable early next week. Regardless of development, this system is likely to produce locally heavy rainfall over portions of western Cuba, the Florida Keys, and the Florida peninsula during the next several days while the system moves northwestward. * 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
