Atlantic Tropical Weather Outlook

2019-08-24 13:46:11| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 241146 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Sat Aug 24 2019 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A broad area of low pressure located inland over South Florida is producing a large area of disorganized showers and thunderstorms that extends eastward over the northwestern Bahamas and the adjacent Atlantic waters. Significant development of the low is unlikely today while it drifts northward over the southern or central Florida peninsula. However, environmental conditions appear conducive for gradual development once the low moves off the east-central coast of Florida over the western Atlantic by Sunday, and a tropical or subtropical depression is likely to form early next week while the system moves northeastward offshore of the southeastern United States coast. Regardless of development, locally heavy rains are possible over the northwestern Bahamas and the southern and central Florida peninsula through the weekend. Interests in the northwestern Bahamas, the Florida peninsula, and the southeastern coast of the United States should monitor the progress of this system. The Air Force Reserve Hurricane Hunter aircraft scheduled to investigate the system this afternoon could be postponed if the center of the low remains inland. Another aircraft is scheduled to investigate the system on Sunday. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. Showers and thunderstorms associated with a small area of low pressure located about 950 miles east of the Windward Islands are showing some signs of organization. Environmental conditions appear conducive for additional development, and a tropical depression is likely to form during the next day or two while the low moves westward to west-northwestward at 10 to 15 mph. Conditions appear less favorable for development when the low reaches the Lesser Antilles and eastern Caribbean Sea by the middle of next week. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...80 percent. $$ Forecaster Beven

A broad area of low pressure located inland over South Florida continues to produce a large area of disorganized showers and thunderstorms that extend eastward over the northwestern Bahamas and the adjacent Atlantic waters. Significant development of the low is unlikely today while it drifts northward over the southern Florida peninsula. Environmental conditions appear conducive to support gradual development once the low moves off the east-central coast of Florida over the western Atlantic by Sunday, and a tropical or subtropical depression is likely to form early next week while the system moves northeastward offshore of the southeastern United States coast. Regardless of development, locally heavy rains are possible over the northwestern Bahamas and the southern and central Florida peninsula through the weekend. Interests in the northwestern Bahamas, the Florida peninsula, and the southeastern coast of the United States should monitor the progress of this system. The Air Force Reserve Hurricane Hunter aircraft scheduled to investigate the system later today could be postponed if the center of the low remains inland over Florida. Another aircraft is scheduled to investigate the system on Sunday. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. Showers and thunderstorms associated with a small area of low pressure located about 1050 miles east of the Windward Islands are showing some signs of organization. Environmental conditions appear conducive for additional development, and a tropical depression is likely to form over the weekend or early next week while the low moves westward to west-northwestward at 10 to 15 mph. Conditions appear less favorable for development when the low reaches the Lesser Antilles and eastern Caribbean Sea by the middle of next week. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...70 percent. $$ Forecaster Berg

000 ABNT20 KNHC 232334 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM 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 several hundred miles west of the Azores. A broad area of low pressure located near the coast of southeastern Florida continues to produce a large area of showers and thunderstorms that extend eastward over the northern Bahamas and the adjacent western Atlantic waters. The system has changed little in organization since this afternoon, but environmental conditions are expected to be conducive for gradual development, and a tropical depression is likely to form over the weekend. The low is forecast to move generally northwestward near or over southeastern Florida through tonight, and then move northward to northeastward over the Atlantic near the east coast of central Florida on Saturday. After that, the system is expected to move northeastward offshore of the southeastern United States coast. Regardless of development, locally heavy rains are possible over the northwestern Bahamas and the southern and central Florida peninsula through the weekend. Interests in the northwestern Bahamas, the Florida peninsula, and the southeast coast of the United States should monitor the progress of this system. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the system on Saturday, if necessary. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. Satellite imagery suggests that the circulation associated with an area of low pressure located about 1100 miles east-southeast of the Windward Islands has become better defined, but the thunderstorm activity is limited at this time. Environmental conditions appear conducive for additional development, and a tropical depression is likely to form over the weekend or early next week while it moves generally westward to west-northwestward near 15 mph. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...70 percent. $$ Forecaster Brown

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. 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. $$ Forecaster Beven
