en Español 000 ABNT20 KNHC 231152 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Wed Sep 23 2026 For the North Atlantic...Caribbean Sea and the Gulf of America: Far Eastern Tropical Atlantic: An area of low pressure, associated with a tropical wave that just moved off the west coast of Africa, has formed about 600 miles southeast of the Cabo Verde Islands. This system could become a short-lived tropical depression on Thursday or Friday while it moves northwestward to northward. However, strong upper-level winds should end the opportunity for development by the weekend. Interests in the Cabo Verde Islands should monitor the progress of this system as gusty winds and areas of heavy rain are possible there by the end of the week. * Formation chance through 48 hours...low...30 percent. * Formation chance through 7 days...medium...40 percent. Central Subtropical Atlantic (Former Tropical Storm Fay): A low pressure system, formerly Tropical Storm Fay, is located about 800 miles southwest of the Azores. Shower activity associated with the low has increased this morning. However, significant re-development of this system is unlikely while it moves generally westward over the next couple of days. By the weekend, increasingly strong upper-level winds should inhibit re-development. * Formation chance through 48 hours...low...20 percent. * Formation chance through 7 days...low...20 percent. $$ Forecaster Pasch
