000 WTNT33 KNHC 311442 TCPAT3 BULLETIN Post-Tropical Cyclone Melissa Advisory Number 41 NWS National Hurricane Center Miami FL AL132025 1100 AM AST Fri Oct 31 2025 ...MELISSA BECOMES A POWERFUL POST-TROPICAL CYCLONE OVER THE NORTHWEST ATLANTIC... ...THIS IS THE LAST NHC ADVISORY... SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...39.0N 60.5W ABOUT 520 MI...840 KM NNE OF BERMUDA ABOUT 650 MI...1045 KM SW OF CAPE RACE NEWFOUNDLAND MAXIMUM SUSTAINED WINDS...85 MPH...140 KM/H PRESENT MOVEMENT...NE OR 40 DEGREES AT 48 MPH...78 KM/H MINIMUM CENTRAL PRESSURE...973 MB...28.74 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: None. A brief period of heavy rain and gusty winds is possible over the southern Avalon Peninsula of Newfoundland tonight. For more information on impacts in Canada, see the Canadian Hurricane Center website at https://weather.gc.ca/hurricane/index_e.html DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone Melissa was located near latitude 39.0 North, longitude 60.5 West. The post-tropical cyclone is moving toward the northeast near 48 mph (78 km/h). This general motion is expected to continue into Saturday, followed by a gradual slowdown and turn toward the east-northeast later this weekend. On the forecast track, the center of Melissa is expected to pass to the southeast of the Avalon Peninsula of Newfoundland as a post-tropical cyclone tonight. Maximum sustained winds have decreased to near 85 mph (140 km/h) with higher gusts. Gradual weakening is forecast during the next few days. Hurricane-force winds extend outward up to 105 miles (165 km) from the center and tropical-storm-force winds extend outward up to 275 miles (445 km). The estimated minimum central pressure is 973 mb (28.74 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Melissa can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Gusty winds are possible over the southern Avalon Peninsula of Newfoundland tonight. RAINFALL: A brief period of heavy rain is possible over the southern Avalon Peninsula of Newfoundland tonight. SURF: Swells generated by Melissa will continue to affect portions of the Bahamas, the Turks and Caicos Islands, Bermuda, the Northeastern United States coast and portions of Atlantic Canada during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. 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 Hagen

000 WTNT43 KNHC 311443 TCDAT3 Post-Tropical Cyclone Melissa Discussion Number 41 NWS National Hurricane Center Miami FL AL132025 1100 AM AST Fri Oct 31 2025 Melissa no longer possesses organized convection, and is now merging with a warm front extending eastward and a cold front extending toward the southwest. Therefore, Melissa is now a post-tropical cyclone. Melissa still has hurricane-force winds, especially in the southeastern semicircle, as shown in Thursday evening ASCAT data and also shown in the latest global model fields for the current time of 15Z. The initial intensity is lowered slightly to 75 kt, mainly based on forecast continuity. Large swells from Melissa are spreading over much of the western Atlantic, resulting in hazardous marine conditions in this region. The post-tropical cyclone is racing northeastward, or 40 degrees at 42 kt. This motion should continue into Saturday within the flow ahead of an upper-level trough. Track guidance is in excellent agreement that the center of post-tropical Melissa will pass near, but to the southeast of, the Avalon Peninsula of Newfoundland late tonight, bringing the potential for some gusty winds and heavy rain. Later this weekend, Melissa is forecast to turn east-northeastward while interacting with a higher-latitude, upper-level low over the North Atlantic. Very little change has been made to the NHC track forecast, which lies very close to the average of the GFS and ECMWF deterministic models (GFEX). Global models indicate that Melissa will continue to be a large and strong extratropical cyclone for the next couple of days as it traverses the North Atlantic. Only gradual weakening is expected through the weekend, with the system forecast to have hurricane-force winds for another 24 h and still be a storm-force cyclone in 60 hours. The NHC intensity forecast is at the high end of the guidance suite through 60 hours. By early next week, global models show the large system weakening further as it begins to join up with a large and elongated area of low pressure over the far northeastern Atlantic, and the system should be absorbed and dissipated just beyond the 96-hour point. Key Messages: 1. Post-storm safety: Follow advice of local officials and avoid areas of downed power lines and flooding. Ensure generators are properly ventilated and placed outside at least 20 feet away from dwellings and garages to avoid carbon monoxide poisoning. During clean up, be careful when using chainsaws and power tools. Drink plenty of water to avoid heat exhaustion.
