TROPICAL STORM DOUGLAS DISCUSSION NUMBER 25
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014
200 PM PDT FRI JUL 04 2014
Even though Douglas has been devoid of deep convection for about six
hours, a 1716 UTC ASCAT overpass indicated a patch of wind near
tropical-storm strength north-northwest of the center. Therefore,
the initial intensity is held at 35 kt for this advisory. With the
cyclone now over 23-degree C water and embedded in a dry and very
stable air mass, it seems unlikely that any deep convection would
re-develop. Douglas is forecast to degenerate into a remnant low
within 12 hours, and the circulation of the decaying cyclone should
gradually spin down during the next couple of days.
The initial motion estimate is 305/05, a little to the left than
before. A low-level ridge of high pressure west of the southern
tip of the Baja California peninsula should keep the cyclone moving
west-northwestward or northwestward until dissipation in about 3
days.
