Tropical Storm DOUGLAS


ZCZC MIATCDEP4 ALL
TTAA00 KNHC DDHHMM

TROPICAL STORM DOUGLAS DISCUSSION NUMBER  17
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP042014
200 PM PDT WED JUL 02 2014

Convection associated with Douglas is quickly losing its
organization.  In addition, a 1758 UTC ASCAT-B pass indicated that
the maximum winds have decreased slightly, and the initial
intensity is set at 35 kt for this advisory.  Visible satellite
images show that dry and stable air continues to infiltrate into
Douglas's circulation, and along with decreasing sea surface
temperatures, will contribute to additional weakening during the
next couple of days.  Douglas is now forecast to become a tropical
depression in 12 hours and degenerate into a remnant low by 36
hours.

Douglas is creeping north-northwestward with an initial motion of
330/2 kt.  However, the cyclone is expected to turn back to the
northwest later tonight and eventually accelerate to the
west-northwest by 48 hours when mid-level ridging builds over the
western United States.  Low-level ridging is forecast to steer the
remnant low west-northwestward to westward between days 3 and 5.
The track guidance is tightly clustered on this advisory cycle, and
no significant changes were required to the NHC track forecast.
