TROPICAL STORM FRANK DISCUSSION NUMBER 26
NWS NATIONAL HURRICANE CENTER MIAMI FL EP072016
800 PM PDT WED JUL 27 2016
The cloud pattern is gradually deteriorating, and microwave data
show that the low-level center is becoming even more separated from
the residual thunderstorm activity. However, the circulation is
still vigorous, and subjective satellite intensity estimates from
TAFB and SAB and objective numbers from CIMSS support an initial
intensity of 45 kt.
Given that Frank's entire circulation is moving over waters with
temperatures of less than 24C, the thunderstorm activity should
diminish resulting in gradual weakening. Frank is anticipated to
become a remnant low by Thursday.
The cyclone is moving toward the west-northwest or 300 degrees at 7
kt, steered by the deep-layer flow around the subtropical high.
This motion will likely continue for a day until Frank becomes a
shallow system and moves westward within t
he trade winds. There is
good agreement in the track models, and the NHC forecast is in the
middle the guidance envelope.
