TROPICAL STORM FRANK DISCUSSION NUMBER  24
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP072016
800 AM PDT WED JUL 27 2016

Frank is quickly weakening today, with a shrinking area of deep
convection near and northwest of the center.  A blend of the
TAFB/SAB Dvorak T/CI numbers gives an initial wind speed of 55 kt
for this advisory.  Steady weakening is expected due to the cyclone
moving over progressively colder waters and into a more stable
airmass. The official intensity forecast remains near the latest
model consensus, IVCN, and Frank should degenerate into a remnant
low by tomorrow afternoon.

Microwave data indicate the storm continues moving 295/10 kt. Frank
should turn westward and slow down as the cyclone becomes a weak and
shallow remnant low steered by the low-level ridge.  Models have
shifted a little southward on this cycle, and the official forecast
follows that trend.
