Atlantic Tropical Weather Outlook

2021-08-09 01:45:41| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 082345 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Sun Aug 8 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A low pressure system located about 400 miles east-southeast of the Leeward Islands is producing disorganized showers and thunderstorms. However, environmental conditions are expected to be conducive for gradual development over the next few days, and a tropical depression could form while the low moves west-northwestward at about 15 mph. The disturbance is forecast to reach portions of the Lesser Antilles by late Monday, and then move near the Virgin Islands and Puerto Rico on Tuesday, and be near Hispaniola around the middle of this week. Tropical storm watches or warnings could be required with shorter-than-normal lead times for the Leeward Islands, Virgin Islands, and Puerto Rico. In addition, heavy rains and flooding are likely for the Leeward Islands, Virgin Islands, Puerto Rico. Interests in those areas should monitor the progress of this system. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...medium...60 percent. Disorganized showers and thunderstorms have changed little in association with an elongated low pressure system located over the tropical Atlantic about midway between the Cabo Verde Islands and the Lesser Antilles. Although environmental conditions appear to be only marginally conducive for development, this system could still become a tropical depression later this week while it moves toward the west or west-southwest at around 10 mph. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...medium...40 percent. $$ Forecaster Stewart
