ZCZC MIATCDEP2 ALL TTAA00 KNHC DDHHMM 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 on the web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFEPI.shtml.
