Post-Tropical Cyclone Kristy Discussion Number  19
NWS National Hurricane Center Miami FL       EP132018
800 AM PDT Sat Aug 11 2018

Cold waters and wind shear have taken a toll on Kristy.  The cloud
pattern has degenerated considerably, and it now consists of a
tight swirl of low clouds with some patches of mid- to high-level
clouds. It is estimated that the winds have decreased to 30 kt with
some isolated spots of higher gusts. The cyclone will continue over
cold waters, and although regeneration is not anticipated, some
intermittent showers could still develop before dissipation occurs
in a couple of days.

Since the post-tropical cyclone is a shallow system, it is now being
steered toward the west-northwest or 300 degrees at 4 kt by the
low-level trade winds. This general motion with a gradual turn to
the west is anticipated during the next day or so.

This is the last advisory issued by NHC on this system.
