000 ABNT20 KNHC 272336 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 800 PM EDT SUN SEP 27 2015 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center has issued the last advisory on post-tropical cyclone Ida, located about 1000 miles east-northeast of the northern Leeward Islands. A well-defined low pressure system located over the south-central Gulf of Mexico about 100 miles north of the northeastern Yucatan Peninsula is producing a large area of cloudiness and thunderstorms that extends from the eastern Gulf of Mexico southward across western Cuba and into the northwestern Caribbean Sea. Upper-level winds are expected to be only marginally conducive for development while the system moves northward toward the northern Gulf Coast during the next couple of days. However, only a slight deviation of the motion toward the northeast would place the system in less hostile environmental conditions. Regardless of tropical cyclone formation, this large disturbance is likely to produce locally heavy rainfall over portions of the northeastern Gulf Coast, Florida, and the southeastern United States during the next few days. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the low on Monday, if necessary. For additional information on this 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...medium...40 percent * Formation chance through 5 days...medium...40 percent Thunderstorm activity has increased and become better organized today in association with a low pressure system that is located about midway between the central Bahamas and Bermuda. Additional development of this system is likely, and a tropical depression could form tonight or on Monday while the low moves slowly toward the northwest. By Tuesday, development is not expected due to unfavorable upper-level winds. For more information on this system, see High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...high...70 percent * Formation chance through 5 days...high...70 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 Stewart
