Tropical Depression Eleven-E Discussion Number 4
NWS National Hurricane Center Miami FL EP112017
300 AM MDT Sat Aug 05 2017
The center of the depression moved over Socorro Island, Mexico
between 0400 and 0500 UTC. A Mexican Navy automatic weather
station located in that island reported a well defined wind shift
associated with the circulation and 20 to 25 kt winds in gusts. A
recent ASCAT pass shows a few vectors of 30 kt, and this will be the
intensity in this advisory.
The depression has been decapitated by strong upper-level easterly
winds, and the low-level and mid-level centers are now separated by
at least 230 n mi. There are only a few patches of deep convection
left. Since the shear environment is forecast to persist or even
increase, the NHC forecast calls for the depression to become a
remnant low in about 12 hours or so.
The low-level swirl associated with the center of the depression is
moving toward the northwest or 315 degrees at 8 kt around the
periphery of a subtropical ridge. Since no changes in the steering
pattern is forecast by global models, this general motion is
expected to continue until dissipation in a day or so.
