000 WTNT31 KNHC 210836 TCPAT1 BULLETIN Tropical Storm Fay Advisory Number 8 NWS National Hurricane Center Miami FL AL062026 900 AM GMT Mon Sep 21 2026 ...FAY BEGINS TO WEAKEN... SUMMARY OF 900 AM GMT...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...33.8N 32.1W ABOUT 405 MI...655 KM SW OF THE AZORES MAXIMUM SUSTAINED WINDS...65 MPH...100 KM/H PRESENT MOVEMENT...SSE OR 155 DEGREES AT 2 MPH...4 KM/H MINIMUM CENTRAL PRESSURE...997 MB...29.44 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 900 AM GMT (0900 UTC), the center of Tropical Storm Fay was located near latitude 33.8 North, longitude 32.1 West. Fay is moving very slowly toward the south-southeast near 2 mph (4 km/h). A faster motion to the southwest is anticipated during the next few days. Maximum sustained winds have decreased to near 65 mph (100 km/h) with higher gusts. Continued weakening is forecast, and Fay could degenerate to a post-tropical cyclone in a day or two. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 300 PM GMT. $$ Forecaster Cangialosi

000 WTNT41 KNHC 210836 TCDAT1 Tropical Storm Fay Discussion Number 8 NWS National Hurricane Center Miami FL AL062026 900 AM GMT Mon Sep 21 2026 Fay is now feeling the effects of strong vertical wind shear. Satellite imagery indicates that the circulation has become significantly vertical tilted, with the low-level center now well north-northwest of the mid-level center. The initial intensity is nudged down to 55 kt, which lies at the high end of the latest satellite intensity estimates. Continued strong northerly vertical wind shear, along with intrusions of dry air should cause Fay to steadily weaken over the next few days. In fact, simulated satellite images from the GFS and ECMWF models show deep convection completely dissipating within the next 24 hours due to the harsh atmospheric conditions. Based on the latest guidance and satellite trends, the new forecast calls for a faster rate of weakening, with the transition to a remnant low now expected by 48 hours and dissipation in 4-5 days. This forecast lies near the middle of the guidance envelope. Fay appears to have turned southward at a slow pace, as expected, as the mid- to upper-level trough over the north Atlantic lifts out. A faster southwestward motion is forecast over the next few days as a low- to mid-level ridge becomes established to the northeast of the cyclone. This pattern should keep the system over the open Atlantic through dissipation later in the week. Little change was made to the previous track forecast, and this prediction is in best agreement with the Google DeepMind ensemble mean and HCCA.
