SUMMARY OF 900 AM GMT...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...33.5N 43.9W ABOUT 1210 MI...1950 KM E OF BERMUDA ABOUT 995 MI...1600 KM WSW OF THE AZORES MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...ESE OR 120 DEGREES AT 5 MPH...7 KM/H MINIMUM CENTRAL PRESSURE...1006 MB...29.71 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 Hanna was located near latitude 33.5 North, longitude 43.9 West. Hanna is moving toward the east-southeast near 5 mph (7 km/h). A turn toward the east-northeast is expected later today with an increase in forward speed on Thursday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual weakening is expected today and Hanna should become a post-tropical remnant low by tonight. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1006 mb (29.71 inches).

000 WTNT43 KNHC 300843 TCDAT3 Tropical Storm Hanna Discussion Number 8 NWS National Hurricane Center Miami FL AL082026 900 AM GMT Wed Sep 30 2026 This morning's conventional satellite presentation consists of a poorly organized, severely sheared tropical cyclone. Although the associated deep convection is more than 170 mi east of the surface center, a 0318 UTC OSCAT-3 scatterometer pass indicated that the cyclone is still producing a small area of tropical-storm-force winds. Based on this satellite-derived wind data, the initial intensity is held at 35 kt. Hanna should gradually weaken today due to increasing deep-layer northwesterly shear, and continued dry air entrainment. The GFS/ECMWF simulated satellite/IR imagery prediction shows Hanna quickly losing organized deep convection and becoming a post-tropical cyclone by tonight and opening into a trough of low pressure over the weekend. The global models and the statistical Decay-SHIPS intensity guidance are also indicating that the remnants of Hanna could merge with a baroclinic system on Friday. No significant changes were made to the NHC intensity forecast. Hanna's initial motion is estimated to be east-southeastward, or 120/4 kt. This general motion should continue this morning while the cyclone remains in the low- to mid-level mid-latitude westerly steering flow provided by a longwave trough moving over the northeastern Atlantic. By this evening, Hanna should turn east-northeastward while the cyclone degenerates into a swirl of low clouds and is steered by the low-level flow. The official forecast is adjusted to the right of the previous advisory and is nudged toward the HFIP HCCA guidance.
