Post-Tropical Cyclone Andres Forecast Discussion Number 10

2021-05-11 16:38:37| National Hurricane Center (East Pacific)

Issued at 900 AM MDT Tue May 11 2021 000 WTPZ41 KNHC 111438 TCDEP1 Post-Tropical Cyclone Andres Discussion Number 10 NWS National Hurricane Center Miami FL EP012021 900 AM MDT Tue May 11 2021 Hostile environmental conditions have reduced Andres to an exposed, low-level cloud swirl. Although a small burst of convection was noted earlier this morning over 100 n mi northeast of the center, Andres has been without organized deep convection near its center for over 12 hours. Therefore, the cyclone has become a remnant low, and this will be the final NHC advisory on Andres. The remnant low is moving just south of due west and will continue moving westward within the low-level trade wind flow until it dissipates on Wednesday night. Overnight scatterometer data indicated that 20-25 kt winds were confined to the northwest quadrant of Andres, between the cyclone and a subtropical ridge to its northwest. Continued weakening is expected as the remnant low moves into a drier, more stable environment with increasing wind shear and decreasing sea-surface temperatures. This is the last NHC advisory on Andres. For additional information on the remnant low please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php FORECAST POSITIONS AND MAX WINDS INIT 11/1500Z 15.8N 111.4W 25 KT 30 MPH...POST-TROPICAL 12H 12/0000Z 15.8N 112.3W 20 KT 25 MPH...POST-TROP/REMNT LOW 24H 12/1200Z 15.7N 113.5W 20 KT 25 MPH...POST-TROP/REMNT LOW 36H 13/0000Z...DISSIPATED $$ Forecaster Reinhart/Brown
