Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Fri Aug 23 2019 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Chantal, located about 765 miles west of the Azores. 1. Surface and radar data indicate that a weak area of low pressure is located just east of the upper Florida Keys and the southeastern coast of the Florida peninsula. This system is producing a large area of disorganized cloudiness and showers that extends primarily northeast of the center over the northwestern Bahamas and the adjacent Atlantic Ocean. The low is forecast to move near or over the Florida peninsula through tonight, which should limit development during that time. Environmental conditions appear conducive for development once the system moves northeastward back over the Atlantic waters on Saturday. A tropical depression is likely to form this weekend or early next week while the low moves from near the coast of east-central Florida to offshore of the southeastern United States coast. Regardless of development, locally heavy rains are possible over the northwestern Bahamas and southern and central Florida through the weekend. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 5 days...high...70 percent. 2. Showers and thunderstorms have increased since yesterday in association with a tropical wave located about 1400 miles east-southeast of the Windward Islands. Additional slow development of this system is possible during the next few days as it moves generally westward at about 15 mph. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent.
