Post-Tropical Cyclone JOHN
ZCZC MIATCDEP2 ALL TTAA00 KNHC DDHHMM Post-Tropical Cyclone John Discussion Number 20 NWS National Hurricane Center Miami FL EP122018 800 AM PDT Fri Aug 10 2018 John's convection vanished around 0430 UTC, and the cyclone now consists of a tight swirl of low clouds moving over a 22 degree Celsius ocean. Given the lack of convection, the system has been classified as a remnant low with 30-kt winds in this last advisory. The low is moving toward the northwest at 9 kt, and this general motion will likely continue until dissipation in a couple of days. Swells associated with the remnants of John continue to affect portions of the coasts of the Baja California peninsula and southern California, but will soon begin to subside. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. This is the last NHC advisory on John.
