477 ABNT20 KNHC 071730 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Sat Aug 7 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Showers and thunderstorms associated with a broad area of low pressure located a little more than 100 miles south of the southwesternmost Cabo Verde Islands have increased today. Some gradual additional development is possible during the next day or so but strong upper-level winds and cooler waters are likely to prevent significant development after that time. The system is expected to move generally west-northwestward to northwestward across the eastern tropical Atlantic at 10 to 15 mph. Regardless of development, locally heavy rainfall and gusty winds are possible over portions of the southernmost Cabo Verde Islands tonight and Sunday. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...low...30 percent. A small but well-defined area of low pressure located over the tropical Atlantic about a thousand miles west of the Cabo Verde Islands continues to produce limited shower activity. Environmental conditions are expected to become a little more favorable for gradual development over the next several days, and this system could become a tropical depression by the middle of next week. The system is forecast to drift toward the west-southwest or west during the next couple of days, and then move a little faster toward the west-northwest early next week. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...40 percent. A tropical wave located over the west-central tropical Atlantic is producing limited shower and thunderstorm activity. Significant development of this system is not anticipated as it moves west-northwestward across the Lesser Antilles and eastern Caribbean Sea during the early to middle part of next week. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...10 percent. $$ Forecaster Brown
