Post-Tropical Cyclone Henriette Discussion Number   7
NWS National Hurricane Center Miami FL       EP092019
800 AM PDT Tue Aug 13 2019

The system has been devoid of deep convection for about 12 hours,
and therefore, it has degenerated into a remnant low.  The
post-tropical cyclone is moving through an environment of
dry, stable air and over cooler SSTs, which should cause the low to
dissipate in a day or so.

The motion is west-northwestward, or 285/10 kt.  A low-level ridge
to the north of the system should steer Henriette's remnants on a
west-northwestward to westward heading until dissipation.  The
official track forecast is close to the multi-model consensus,

This is the last NHC advisory on Henriette.  For additional
information on the remnant low please see High Seas

header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at
