ABNT20 KNHC 020539 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Fri Sep 2 2022 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Active Systems: The National Hurricane Center is issuing advisories on Tropical Storm Danielle, located about 925 miles west of the Azores. East of the Leeward Islands (AL91): Satellite imagery indicates there has been little change in the organization of the area of low pressure located several hundred miles east of the Leeward Islands during the past several hours. Although environmental conditions remain only marginally conducive, any additional development of the system over the next few days would lead to the formation of a tropical depression. The disturbance is expected to move slowly west-northwestward, toward the adjacent waters of the northern Leeward Islands. Regardless of development, locally heavy rains may occur over portions of the Leeward Islands during the next couple of days, and interests in that area should monitor the progress of the system. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the system this afternoon, if necessary. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 7 days...high...70 percent. Eastern Tropical Atlantic: Shower activity associated with a broad area of low pressure located just northwest of the Cabo Verde Islands has increased some over the last several hours, but remains poorly organized. This system is moving into an area of less favorable environmental conditions, and significant development is not anticipated. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...10 percent. && Public Advisories on Tropical Storm Danielle are issued under WMO header WTNT35 KNHC and under AWIPS header MIATCPAT5. Forecast/Advisories on Tropical Storm Danielle are issued under WMO header WTNT25 KNHC and under AWIPS header MIATCMAT5.

ABNT20 KNHC 041548 TWOAT Special Tropical Weather Outlook NWS National Hurricane Center Miami FL 1150 AM EDT Tue Oct 4 2022 Special Tropical Weather Outlook to update discussion of the tropical wave east of the Windward Islands For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Eastern Tropical Atlantic (AL91): A broad low pressure system located a few hundred miles west-southwest of the Cabo Verde Islands continues to produce a large area of showers and thunderstorms. Environmental conditions are currently conducive for development, and a tropical depression is likely to form during the next day or so while moving northwestward at about 10 mph over the eastern tropical Atlantic. Upper-level winds are expected to become less conducive for development by Wednesday and Thursday. * Formation chance through 48 hours...high...80 percent. * Formation chance through 7 days...high...80 percent. East of the Windward Islands (AL92): Updated: Visible satellite images and recent satellite-derived wind data suggest that a broad low-level circulation could be forming in association with the tropical wave located a few hundred miles east of the southern Windward Islands. Although the wave is currently being affected by strong upper-level winds, conditions could become more conducive for a tropical depression to form while moving westward at about 15 mph, crossing the Windward Islands tonight and early Wednesday. Conditions appear to become more conducive for development later this week when the system reaches the central and western Caribbean Sea. Regardless of development, locally heavy rainfall and gusty winds are expected over portions of the Windward Islands tonight and Wednesday. Interests in the Windward Islands, the ABC Islands, and the northern coast of Venezuela should monitor the progress of this system. An Air Force Reserve Hurricane Hunter aircraft is currently enroute to investigate this system. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 7 days...high...70 percent. $$ Forecaster Berg NNNN
