Post-Tropical Cyclone Vicente Forecast Discussion Number 17
2018-10-23 16:33:58| National Hurricane Center (East Pacific)
Issued at 1000 AM CDT Tue Oct 23 2018 000 WTPZ43 KNHC 231433 TCDEP3 Post-Tropical Cyclone Vicente Discussion Number 17 NWS National Hurricane Center Miami FL EP232018 1000 AM CDT Tue Oct 23 2018 Satellite imagery indicates that Vicente crossed the coast of the Mexican state of Michoacan a little while ago, and is now inland. The system, if in fact it still has a center, lacks sufficient organized deep convection to be considered a tropical cyclone. Therefore Vicente has become a post-tropical remnant low, and this is the last advisory on this system. The motion is around 330/10 kt. A 12-hour forecast point is shown for continuity, but the cyclone will probably have dissipated by that time. Vicente's remnants, along with southwesterly flow around the larger circulation of Hurricane Willa, will probably continue to produce locally heavy rains over portions of southwestern Mexico into Wednesday.
