Tropical Storm Wilfred Discussion Number   2

There haven't been a lot of changes with Wilfred today, with the 
northern side of the circulation looking rather dry while the 
center remains close to a burst of convection.  The initial wind 
speed is kept 35 kt, closest to the TAFB classification.  Wilfred 
could strengthen some during the next day or so before increasing 
upper-level westerlies winds likely begin by Sunday.  A gradual 
weakening is expected into early next week, though the model 
guidance is in worse agreement than the last advisory due to the 
positioning of an upper-level low.  The forecast continues to 
show the storm ending up on the convergent side of the low and 
dissipating, close to the previous one.  

Wilfred is moving west-northwestward at about 16 kt, after 
accounting for a re-positioning westward.  Most of the guidance 
agrees on a scenario that maintains this track for the next few 
days, with a turn toward the west as the cyclones dissipates.  The 
new forecast is closest to the GFS-based guidance.  Similar to the 
intensity forecast, however, there are some models that suggest 
Wilfred could slow down and turn to the right in a couple of days if 
it is stronger than anticipated.
