TROPICAL DEPRESSION FELICIA DISCUSSION NUMBER 4
NWS NATIONAL HURRICANE CENTER MIAMI FL EP072015
800 PM PDT THU JUL 23 2015
Satellite images indicate that Felicia is weakening. The low-level
center of the system is exposed and the associated deep convection
is confined to the southeastern quadrant of the circulation. The
initial wind speed is lowered to 30 kt based on a blend of the
Dvorak classifications from TAFB, SAB, and UW-CIMSS ADT. This
makes Felicia a tropical depression. Since the depression is
already in a dry and stable airmass and will soon be over cool
water, continued weakening is predicted. The official forecast
shows Felicia becoming a remnant low by 36 hours, but this could
occur even sooner. The remnant low is expected to dissipate in 3
to 4 days.
Felicia is moving northwestward at about 11 kt. The depression is
expected to turn to the west-northwest on Friday and to the west on
Saturday steered by the low-level flow. The official track forecast
is similar to the previous one and in best agreement with a
consensus of the GFS and ECMWF models.
