000 WTNT33 KNHC 012038 TCPAT3 BULLETIN Post-Tropical Cyclone Franklin Advisory Number 49 NWS National Hurricane Center Miami FL AL082023 500 PM AST Fri Sep 01 2023 ...FRANKLIN HAS BECOME A POWERFUL EXTRATROPICAL CYCLONE... ...THIS IS THE FINAL NHC ADVISORY... SUMMARY OF 500 PM AST...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...39.5N 53.8W ABOUT 790 MI...1270 KM NE OF BERMUDA MAXIMUM SUSTAINED WINDS...80 MPH...130 KM/H PRESENT MOVEMENT...NE OR 55 DEGREES AT 17 MPH...28 KM/H MINIMUM CENTRAL PRESSURE...979 MB...28.91 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Franklin was located near latitude 39.5 North, longitude 53.8 West. The post-tropical cyclone is moving toward the northeast near 17 mph (28 km/h). A faster northeastward motion is expected during the next couple of days, followed by a turn to the east-northeast. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Little change in strength is expected through tonight, but gradual weakening is forecast this weekend into early next week. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 255 miles (405 km). The estimated minimum central pressure is 979 mb (28.91 inches). HAZARDS AFFECTING LAND ---------------------- None NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on Franklin. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php $$ Forecaster Reinhart

000 WTNT43 KNHC 012040 TCDAT3 Post-Tropical Cyclone Franklin Discussion Number 49 NWS National Hurricane Center Miami FL AL082023 500 PM AST Fri Sep 01 2023 The satellite appearance of Franklin suggests the cyclone has undergone a warm core seclusion process. Earlier scatterometer data showed a cold front nearing the core of Franklin, and recent visible satellite images suggest the presence of a bent-back occlusion wrapping around the western side of the low that appears to be the focus for the ongoing convection. Also, the latest FSU phase space diagrams from the GFS and ECMWF models show a thickness asymmetry consistent with a warm-core frontal cyclone. Therefore, it appears Franklin has completed its extratropical transition and is no longer a tropical cyclone. Since the earlier scatterometer data, the latest global model fields suggest that baroclinic forcing has resulted in a deepening of the low, with an acceleration of northerly winds to the west of the bent-back front. A blend of wind speeds from the various global models supports an initial intensity of 70 kt. Franklin appears likely to remain a powerful, hurricane-force extratropical cyclone during the next 12 h or so due to baroclinic forcing. Thereafter, the extratropical cyclone is forecast to weaken as the low moves deeper into the mid-latitudes and gradually fills. Franklin is still moving northeastward (50/15 kt) within the flow between a deep-layer trough over the northwestern Atlantic and a subtropical ridge over the central Atlantic. A faster northeastward motion is forecast during the next couple of days, followed by a gradual turn toward the east and east-southeast later in the period as the cyclone rotates around a larger cut-off low over the eastern Atlantic. The global models are finally in better agreement on this outcome, and the track forecast has been adjusted south of the previous one at days 3-5. This is the last advisory issued by the National Hurricane Center on Franklin.
