2020-09-17 07:52:12| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 170552 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Thu Sep 17 2020 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on recently downgraded Tropical Depression Sally, located inland over southeastern Alabama, on Hurricane Teddy, located over the central tropical Atlantic, and on Tropical Storm Vicky, located over the eastern tropical Atlantic. Thunderstorm activity associated with a low pressure system located over the southwestern Gulf of Mexico has increased in coverage and organization this morning. In addition, recent satellite-derived surface wind data indicate that the low has become better defined. Upper-level winds are expected to gradually become more conducive for development, and a tropical depression is likely to form during the next day or so while the low meanders over the southwestern Gulf of Mexico. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the disturbance later today, if necessary. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. An elongated area of low pressure located a few hundred miles south-southwest of the Cabo Verde Islands is producing disorganized shower and thunderstorm activity. Environmental conditions are expected to be conducive for development during the next few days, and a tropical depression could form before upper-level winds become less favorable over the weekend. The low is forecast to move west-northwestward at 10 to 15 mph during the next several days. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 5 days...medium...60 percent. A non-tropical area of low pressure is located over the far northeastern Atlantic Ocean a few hundred miles east-northeast of the Azores. This system is forecast to move east-southeastward and then northeastward at about 10 mph over the next day or two, and its chances of acquiring some subtropical characteristics before it reaches the coast of Portugal late Friday appear to be decreasing. For more information on this system, see High Seas Forecasts issued by Meteo France. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. && High Seas Forecasts issued by Meteo France can be found under WMO header FQNT50 LFPW and available on the web at www.meteofrance.com/previsions-meteo-marine/bulletin/grandlarge/ metarea2 $$ Forecaster Stewart
