Tropical Storm Frank Discussion Number  30

Organized deep convection associated with Frank ceased overnight, 
and the tropical storm should become post-tropical very soon. The 
weakening cyclone is moving northwest near 10 kt, and should 
gradually bend toward the north over the next 36 h, then 
north-northeast by Thursday, steered primarily by the low-level 
flow. The latest TAFB Dvorak Current Intensity estimate is 35 kt, so 
the initial intensity is set at that value. Continued weakening 
will occur over the next few days while Frank gradually spins down 
over cold water with little or no convection to sustain it. 
Dissipation is forecast by nearly all of the dynamical models near 
or just after 60 h. No changes of note were made to the NHC track or 
intensity forecasts, both of which are near the model consensus
