000 WTNT35 KNHC 081438 TCPAT5 BULLETIN Post-Tropical Cyclone Danielle Advisory Number 30 NWS National Hurricane Center Miami FL AL052022 300 PM GMT Thu Sep 08 2022 ...DANIELLE NOW POST-TROPICAL... ...THIS IS THE LAST NHC ADVISORY... SUMMARY OF 300 PM GMT...1500 UTC...INFORMATION ---------------------------------------------- LOCATION...47.9N 31.0W ABOUT 715 MI...1145 KM NNW OF THE AZORES MAXIMUM SUSTAINED WINDS...65 MPH...100 KM/H PRESENT MOVEMENT...NNE OR 20 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...973 MB...28.74 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 300 PM GMT (1500 UTC), the center of Post-Tropical Cyclone Danielle was located near latitude 47.9 North, longitude 31.0 West. The post-tropical cyclone is moving toward the north-northeast near 14 mph (22 km/h). The post-tropical cyclone is forecast to make a gradual counter-clockwise loop during the next 36 h, and then move generally southeastward to east-southeastward through the weekend. Maximum sustained winds have decreased to near 65 mph (100 km/h) with higher gusts. Danielle is forecast to remain a large post-tropical cyclone over the north Atlantic for the next several days, even as its peak winds slowly decrease. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. The estimated minimum central pressure is 973 mb (28.74 inches). HAZARDS AFFECTING LAND ---------------------- None. 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 Meteo France under WMO header FQNT50 LFPW and available on the web at www.meteofrance.com/previsions-meteo-marine/bulletin/grandlarge/ metarea2.

000 WTNT45 KNHC 081438 TCDAT5 Post-Tropical Cyclone Danielle Discussion Number 30 NWS National Hurricane Center Miami FL AL052022 300 PM GMT Thu Sep 08 2022 Satellite imagery this afternoon has shown Danielle develop a clear comma-shaped cloud shield, a hallmark of an extratropical cyclone. In addition, an ASCAT-B pass near 12Z showed a wind shift, indicative of a front, that extended from the center of the cyclone northeastward. Based on these data, Danielle has been classified as post-tropical and this is the last NHC advisory. Peak winds in the ASCAT pass were just above 50 kt, so the intensity of Danielle was lowered slightly to 55 kt. It is worth noting that the peak winds are generally not representative of the impacts associated with extratropical cyclones and gale- to storm-force winds extend well from the center of Danielle. Danielle has begun its long-awaited counterclockwise loop, which should take another 36 to 48 h to complete. After that, the post-tropical cyclone is forecast to move initially southeastward, then eastward as it is caught within the flow of a broader mid-latitude trough moving eastward over the northeastern Atlantic. The track forecast for the post-tropical cyclone is based heavily on the multi-model consensus TVCN. All guidance indicates the cyclone will gradually weaken, both in terms of maximum winds and size through the end of the forecast period. Danielle continues to produce a large area of very rough seas over the central-north Atlantic. More information about the post-tropical cyclone can be found in High Seas Forecasts issued by the UKMET office under WMO header FQNT21 EGRR and on the web at metoffice.gov.uk/weather/specialist-forecasts/coast-and-sea/high- seas-forecast.
