000 ABNT20 KNHC 282328 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 800 PM EDT MON SEP 28 2015 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Eleven, located about midway between the central Bahamas and Bermuda. A sharp trough of low pressure located over the eastern Gulf of Mexico about 150 miles west of Tampa, Florida, continues to produce a large area of showers and thunderstorms over the eastern Gulf of Mexico and portions of the southeastern United States. Surface observations and data from a reconnaissance aircraft from a few hours ago indicate that the system has become elongated. However, the aircraft did find gale-force winds in the eastern portion of the trough. Strong upper-level winds will likely prevent significant development of this system before it moves inland over the northern Gulf coast on Tuesday. Another Air Force Reserve reconnaissance aircraft is scheduled to investigate the disturbance Tuesday morning, if necessary. Regardless of whether or not this system becomes a tropical cyclone, locally heavy rains are likely over portions of the southeastern United States during the next couple of days. For additional information on this weather system, see High Seas Forecasts issued by the National Weather Service and products from your local National Weather Service office. * Formation chance through 48 hours...low...20 percent * Formation chance through 5 days...low...20 percent A large area of disturbed weather over the central Atlantic several hundred miles northeast of the northern Leeward Islands is associated with a frontal trough and the remnants of Ida.
