TROPICAL DEPRESSION DOUGLAS DISCUSSION NUMBER 21
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014
200 PM PDT THU JUL 03 2014
Douglas's low-level center is located just to the west of a small
area of deep convection. Satellite intensity estimates have
decreased a bit since this morning, and a blend of the Final-T and
CI numbers from TAFB, SAB, and the objective ADT support
downgrading Douglas to a 30-kt depression. Continued weakening is
forecast while the depression moves over increasingly cooler
water and into a drier, more stable environment. Douglas is
forecast to degenerate into a remnant low by 24 hours, but it
could become one earlier if the deep convection diminishes soon.
Dissipation is still expected by day 5.
Douglas continues to creep northwestward with an initial motion of
315/2 kt. Low- to mid-level ridging is expected to build over the
western United States during the next 48 hours, which should cause
the remnant low to turn west-northwestward and accelerate by days 3
and 4. The model guidance is in good agreement, and no significant
changes were required to the official NHC track forecast in this
advisory.
