000 ABNT20 KNHC 182316 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 800 PM EDT SAT JUN 18 2016 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A large low pressure system located over the eastern Bay of Campeche about 60 miles north-northeast of Ciudad del Carmen, Mexico, is producing widespread cloudiness and disorganized showers and thunderstorms over much of the Yucatan peninsula and adjacent waters of the Bay of Campeche, southern Gulf of Mexico, and northwestern Caribbean Sea. The low has been nearly stationary during the past several hours, but it is forecast to move west-northwestward to westward at around 10 mph across the Bay of Campeche the next couple of days before moving inland over eastern Mexico. Satellite-derived winds and surface observations indicate that the low has developed a well-defined center of circulation. Although upper-level winds are only marginally conducive, gradual development of this system is expected and a tropical depression could form during the next day or so. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the low Sunday afternoon, if necessary. For additional information on this system, see High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...medium...60 percent * Formation chance through 5 days...medium...60 percent && High Seas Forecasts issued by the National Weather Service are available under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and on the Web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml. $$ Forecaster Stewart
