Post-Tropical Cyclone Cosme Discussion Number   9
NWS National Hurricane Center Miami FL       EP032019
800 AM PDT Mon Jul 08 2019

The combination of cold sea surface temperatures, dry and stable
air, and modest westerly shear has taken a toll on Cosme.  The
cyclone has been devoid of any central deep convection for more
than 12 hours, and has degenerated into a large swirl of mostly
cold-air stratocumulus clouds.  As a result, the system no longer
meets the criteria of a tropical cyclone, and this is the last
advisory.  The winds are estimated to be near 25 kt with higher
gusts based on an overnight ASCAT-C scatterometer pass.  Additional
weakening is forecast, and the remnant low is expected to dissipate
in a couple of days while it moves slowly northwestward over cooler
waters.
