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.

000 WTNT45 KNHC 250232 TCDAT5 Post-Tropical Cyclone Sebastien Discussion Number 23 NWS National Hurricane Center Miami FL AL202019 1100 PM AST Sun Nov 24 2019 Sebastien has lost its tropical characteristics this evening. The deep convection has decoupled from the low-level circulation, and these features are now separated by a distance of 100 n mi and increasing. Two partial ASCAT passes revealed that the surface low is becoming stretched out, and there is some evidence of a boundary, possibly a front, extending northeast from the center. Furthermore, recent observations from Corbo and Flores islands in the Azores indicated a slight temperature decrease as the center passed by to the north of those islands, suggesting that a weak cold front is associated with the the cyclone. Based on all of these data, there is high confidence that Sebastien has transitioned to an extratropical cyclone. The initial advisory intensity is 50 kt which is based on 47 kt winds sampled by the scatterometer and a subjective intensity estimate from TAFB. Post-tropical cyclone Sebastien is moving northeastward at 35 kt, embedded in the strong flow to the southeast of a mid- to upper- level trough. This motion, and the cyclone's current intensity, is expected to persist for the next day or so, before the cyclone merges with a higher-latitude low. The cyclone will likely bring gusty winds and heavy rains to portions of the Azores through Monday morning.
