781 ABNT20 KNHC 181743 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL Issued by the NWS Weather Prediction Center College Park MD 200 PM EDT Tue Aug 18 2020 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A tropical wave over the eastern Caribbean Sea continues to produce an area of disorganized thunderstorms and gusty winds. This wave is moving quickly westward at about 20 mph and significant development is unlikely while it moves across the eastern and central Caribbean Sea during the next day or two. After that time, however, the wave is forecast to slow down, and a tropical depression will likely form late this week or this weekend when it reaches the northwestern Caribbean Sea. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...high...70 percent. An area of low pressure located about 1300 miles east of the Lesser Antilles is producing a concentrated area of showers and thunderstorms. Environmental conditions are conducive for development, and a tropical depression is expected to form within the next couple of days while the system moves west-northwestward at 15 to 20 mph across the central and western portions of the tropical Atlantic. Interests in the Lesser Antilles should monitor the progres of this system. * Formation chance through 48 hours...high...80 percent. * Formation chance through 5 days...high...90 percent. $$ Forecaster Cangialosi
