en Español 047 ABNT20 KNHC 281116 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Mon Sep 28 2026 For the North Atlantic...Caribbean Sea and the Gulf of America: Active Systems: The National Hurricane Center is issuing advisories on Tropical Depression Fay, located well to the southwest of the Azores. Central Subtropical Atlantic (AL91): An area of low pressure located well to the east-northeast of Bermuda is moving quickly eastward. Recent microwave imagery suggests the shower and thunderstorm activity is beginning to show signs of organization, though it is unclear if the system has developed a well-defined circulation given its fast forward motion. While environmental conditions are currently only marginally favorable, this system is now likely to become a tropical depression or storm over the next day or two as it turns east-southeastward and slows down over the central Subtropical Atlantic. Environmental conditions are expected to become unfavorable for further development later this week. * Formation chance through 48 hours...high...70 percent. * Formation chance through 7 days...high...80 percent. $$ Forecaster Papin
