000 ABNT20 KNHC 120536 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 200 AM EDT MON SEP 12 2016 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Satellite derived wind data indicate that the low pressure system located about 900 miles east-northeast of the northern Leeward Islands is producing an area of gale-force winds, but the center of circulation is not well defined. The associated showers and thunderstorms continue to gradually increase and have become a little better organized during the past several hours. If the the circulation of the system becomes better defined, a tropical storm could form later today before upper-level winds become less conducive for development. The low is expected to move northwestward or north-northwestward at 10 to 15 mph over the central Atlantic Ocean during the next few days. For additional information on this system, see High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...high...80 percent * Formation chance through 5 days...high...90 percent Disorganized shower activity continues in association with a disturbance near the central Bahamas. Surface pressures remain high in the area, and there are still no signs of a closed surface circulation. Conditions do not appear conducive for significant development of this disturbance while it moves west-northwestward at 10 to 15 mph. However, locally heavy rainfall is possible over portions of the central and northwestern Bahamas today, and portions of the Florida peninsula on Tuesday. * Formation chance through 48 hours...low...10 percent * Formation chance through 5 days...low...10 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 Cangialosi
