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.
