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
