000 WTNT33 KNHC 292034 TCPAT3 BULLETIN Tropical Storm Hanna Advisory Number 6 NWS National Hurricane Center Miami FL AL082026 900 PM GMT Tue Sep 29 2026 ...HANNA STILL MOVING SOUTHEASTWARD WITH LITTLE CHANGE IN STRENGTH... SUMMARY OF 900 PM GMT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...34.0N 44.5W ABOUT 1175 MI...1895 KM E OF BERMUDA ABOUT 1015 MI...1630 KM W OF THE AZORES MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...SE OR 125 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...1005 MB...29.68 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 900 PM GMT (2100 UTC), the center of Tropical Storm Hanna was located near latitude 34.0 North, longitude 44.5 West. Hanna is moving toward the southeast near 12 mph (19 km/h) and and this motion is forecast to continue with a decrease in forward speed through Wednesday morning, followed by a turn to the east-northeast. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual weakening is expected during the next couple of days, and Hanna is likely to become a post-tropical cyclone by Thursday. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 300 AM GMT. $$ Forecaster Beven

000 WTNT43 KNHC 292032 TCDAT3 Tropical Storm Hanna Discussion Number 6 NWS National Hurricane Center Miami FL AL082026 900 PM GMT Tue Sep 29 2026 Satellite imagery this afternoon shows that the low-level center of Hanna continues mostly exposed to the west of the main convective area. However, the convective area has become more elongated east-west and the system looks more frontal than it did six hours ago due to interaction with a frontal boundary near and to the east of the cyclone. Satellite intensity estimates have changed little since the last advisory, so the initial intensity remains 35 kt based on this and an earlier scatterometer overpass. The initial motion is now 125/10 kt. Hanna is located along the southern edge of the mid-latitude westerlies to the southwest of a large trough over the northeastern Atlantic. This pattern is responsible for the current southeasterly motion. During the next 12-24 h, the flow near the cyclone become more west-to-east, and as Hanna weakens vertically a low-level ridge centered south of the Azores will become the main steering influence. This should result in the cyclone or its remnants turning east-northeastward. The new forecast track is nudged a little to the south of the previous track due mainly to the initial position and motion. Hanna should gradually weaken due to shear, dry air entrainment, and possible merger with the frontal boundary. The latest GFS/ECMWF simulated satellite imagery now forecasts the system to stop producing convection at around 36 h, at which time it would degenerate to a remnant low. After that, the remnant low is expected to weaken to a trough by 96 h.
