Issued at 1100 PM AST Sun Nov 24 2019 000 WTNT35 KNHC 250231 TCPAT5 BULLETIN Post-Tropical Cyclone Sebastien Advisory Number 23 NWS National Hurricane Center Miami FL AL202019 1100 PM AST Sun Nov 24 2019 ...SEBASTIEN NO LONGER A TROPICAL CYCLONE... ...THIS IS THE LAST ADVISORY... SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...41.0N 28.9W ABOUT 230 MI...370 KM NNW OF THE AZORES MAXIMUM SUSTAINED WINDS...60 MPH...95 KM/H PRESENT MOVEMENT...NE OR 55 DEGREES AT 40 MPH...65 KM/H MINIMUM CENTRAL PRESSURE...993 MB...29.33 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. Interests in the Azores should monitor the progress of the remnants of Sebastien. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone Sebastien was located near latitude 41.0 North, longitude 28.9 West. Sebastien is moving toward the northeast near 40 mph (65 km/h) and this motion is expected to continue for the next day or so. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Post-tropical cyclone Sebastien should maintain its intensity before merging with another low during the next day or two. Gale-force winds extend outward up to 220 miles (350 km) from the center. The estimated minimum central pressure is 993 mb (29.33 inches). HAZARDS AFFECTING LAND ---------------------- WIND AND RAIN: The cyclone is expected to bring gusty winds and rain to the Azores through Monday morning. Please see products issued by the Portuguese Institute for the Sea and the Atmosphere (IPMA) for more information. SURF: Swells generated by Sebastien are expected to affect the Azores during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on Sebastien. Additional information on this system can be found in: High Seas Forecasts issued by Meteo France under WMO header FQNT50 LFPW and on the web at: www.meteofrance.com/previsions-meteo-marine/bulletin/grandlarge/ metarea2 $$ Forecaster Latto

Post-Tropical Cyclone Raymond Forecast Discussion Number 11
2019-11-17 15:32:57| National Hurricane Center (East Pacific)
Issued at 800 AM MST Sun Nov 17 2019 000 WTPZ45 KNHC 171432 TCDEP5 Post-Tropical Cyclone Raymond Discussion Number 11 NWS National Hurricane Center Miami FL EP202019 800 AM MST Sun Nov 17 2019 Raymond has degenerated into a remnant low with 25-kt winds. Satellite images indicate that the circulation is elongated and that the thunderstorm activity is well removed from the area of minimum pressure due to very strong wind shear. In addition, observations from the Mexican Navy automatic station at Isla Socorro which is located near Raymond indicate that winds are between 15 and 20 kt. The low is moving northward around 14 kt, but this motion is uncertain since the circulation is elongated and poorly defined. Raymond's remnants are expected to move northward and then north-northwestward and eventually become absorbed by a large developing trough west of the Baja California peninsula in about 24 to 36 hours. The combination of the remnants of Raymond and the developing trough west of the peninsula will bring heavy rains into southern portions of the Baja California peninsula over the next day or two. These rains could cause life-threatening flash flooding. This is the last NHC advisory on Raymond. For additional information about the remnant low, please see High Seas Forecasts issued by the National Weather Service under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php FORECAST POSITIONS AND MAX WINDS INIT 17/1500Z 19.1N 111.1W 25 KT 30 MPH...POST-TROP/REMNT LOW 12H 18/0000Z 21.0N 111.0W 20 KT 25 MPH...POST-TROP/REMNT LOW 24H 18/1200Z 23.5N 112.0W 20 KT 25 MPH...POST-TROP/REMNT LOW 36H 19/0000Z...DISSIPATED $$ Forecaster Avila
