POST-TROPICAL CYCLONE AGATHA DISCUSSION NUMBER 13
NWS NATIONAL HURRICANE CENTER MIAMI FL EP022016
800 PM PDT MON JUL 04 2016
Agatha has been devoid of deep convection for about 12 hours, and
since the cyclone continues to move into an environment of very dry
mid-level air, cool water, and strong shear, organized deep
convection is unlikely to return. On this basis, Agatha has been
declared a remnant low, and this is the last NHC advisory. The
initial wind speed of 30 kt is based on the earlier ASCAT data, and
could be a little generous. Given the hostile conditions, the
remnant low should continue to weaken and is expected to dissipate
in 2 to 3 days.
The cyclone has been moving generally westward or 280/10 kt, and is
forecast to continue westward in the low-level easterly flow until
dissipation occurs. Additional information on the remnant low can
be found in High Seas Forecasts issued by the National Weather
Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and
