000 WTNT33 KNHC 300234 TCPAT3 BULLETIN Tropical Storm Hanna Advisory Number 7 NWS National Hurricane Center Miami FL AL082026 300 AM GMT Wed Sep 30 2026 ...HANNA HOLDING STEADY WHILE MAINTAINING A SOUTHEASTWARD TRACK... SUMMARY OF 300 AM GMT...0300 UTC...INFORMATION ---------------------------------------------- LOCATION...33.7N 43.6W ABOUT 1230 MI...1980 KM E OF BERMUDA ABOUT 975 MI...1565 KM WSW OF THE AZORES MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...SE OR 130 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 300 AM GMT (0300 UTC), the center of Tropical Storm Hanna was located near latitude 33.7 North, longitude 43.6 West. Hanna is moving toward the southeast near 12 mph (19 km/h). This motion is forecast to continue with a decrease in forward speed through morning, followed by a turn to the east-northeast. Maximum sustained winds remain 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 tonight or 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 900 AM GMT. $$ Forecaster Pierce/Cangialosi

000 WTNT43 KNHC 300235 TCDAT3 Tropical Storm Hanna Discussion Number 7 NWS National Hurricane Center Miami FL AL082026 300 AM GMT Wed Sep 30 2026 Visible and infrared satellite imagery shows that the low-level center remains exposed to the west of the main convection area. The convective pattern has become even more elongated west-east, likely influenced by the nearby frontal boundary. A 0032 UTC METOP-C scatterometer pass shows peak winds of 33 kt in the northeast quadrant. The latest TAFB Dvorak fix was T2.5/35 kt, aligning well with the mostly unchanged UW-CIMSS objective estimates. Based on all of these data, the initial intensity remains 35 kt. The initial motion remains southeastward, now 130/10 kt, as Hanna is moving along the southern edge of the mid-latitude westerlies to the southwest of a large trough over the northeastern Atlantic. During the next 1224 h, the flow near the cyclone will 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 updated NHC forecast track was largely unchanged from the previous advisory and remains close to the corrected multi-model consensus (HCCA). Hanna is forecast to gradually weaken as it persists in a moisture-starved environment, with moderate to strong vertical wind shear prevailing over the next 48 to 72 h. The latest GFS/ECMWF simulated satellite imagery now forecasts the system to stop producing convection in 24-36 h, at which time it would degenerate into a remnant low. After that, the remnant low is expected to open into a trough by 96 h. However, it is possible that the system becomes a post-tropical system sooner if it merges with the nearby front.
