Post-Tropical Cyclone Andrea Discussion Number 5
NWS National Hurricane Center Miami FL AL012019
500 PM AST Tue May 21 2019

The cyclone has lacked deep convection since early this morning, and therefore it no longer qualifies as either a tropical or a subtropical cyclone. Dry mid-level air, the influence of an upper-level low, and marginal SSTs should preclude re-development. The cyclone is likely to dissipate in a day or so as it becomes absorbed into a frontal zone.

Post-tropical Andrea has turned to the east-northeast and the motion is about 070/7. The system should move mainly eastward within the mid-level westerlies until dissipation.

This is the last advisory on Andrea. 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
