    Post-Tropical Cyclone Andrea Discussion Number 3
    NWS National Hurricane Center Miami FL AL012025
    1100 PM AST Tue Jun 24 2025

    Andrea is now a remnant low. The system has lacked deep convection
    since earlier this morning and is unlikely to redevelop any while
    traversing increasingly cold sea-surface temperatures, strong
    northeasterly vertical wind shear, and very dry mid-level air.
    Therefore, this will be the final advisory on Andrea. Scatterometer
    data received after the last advisory also indicates winds have
    decreased to about 30 kt. The remnant low should continue to spin
    down, with the various global and regional model guidance showing
    the circulation opening up into a surface trough in about 24 hours.

    The initial motion is 060/17 kt. This motion is expected to continue
    until the remnant low dissipates. 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
