000 WTNT43 KNHC 121442 TCDAT3 Remnants Of Leslie Discussion Number 41 NWS National Hurricane Center Miami FL AL132024 300 PM GMT Sat Oct 12 2024 ASCAT-B data valid near 1300 UTC indicated that Leslie's fast forward motion has caused it to open into a trough. Therefore, this will be the last NHC advisory on Leslie. The ASCAT data indicated that winds of 40-45 kt are still present on the east side of Leslie's remnants, where it continues to produce limited deep convection. A mid-latitude frontal system is nearing the remnants of Leslie, and the two systems are expected to merge within the next 12 h or so, marking Leslie's full transition to a post-tropical cyclone. It is possible that Leslie will redevelop a closed circulation as a non-tropical low at that point. The cyclone is expected to turn eastward on Sunday, bringing it very near or over the Azores late Sunday and through early Monday. By Monday afternoon, Leslie's center is expected to become poorly defined again as it interacts with another weaker mid-latitude cyclone to the east of the Azores.
