 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.
