Post-Tropical Cyclone Frank Discussion Number  31
NWS National Hurricane Center Miami FL       EP072022
200 PM PDT Tue Aug 02 2022

Frank has failed to produce organized deep convection since last 
night, and the system has been reduced to a well-defined low-level 
cloud swirl over the open waters of the eastern Pacific Ocean. Since 
Frank no longer satisfies the criteria of a tropical cyclone, this 
will be the final NHC advisory on now post-tropical Frank.

The cyclone is expected to gradually turn northward during the next 
couple of days as it moves around the western periphery of a distant 
low-level ridge. Although Frank is believed to be still producing 
some 34-kt winds in its northeastern quadrant, weakening is expected 
through midweek as the cyclone continues to spin down over cool 
SSTs. The system is forecast to open into a trough and dissipate by 
early Friday. For additional information on the post-tropical 
cyclone 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
