404 WTNT41 KNHC 250245 TCDAT1 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.
