Tropical Storm Celia Discussion Number  27

The organization of Celia has deteriorated this morning.  The 
low-level center is completely exposed to the north of a 
ragged-looking area of convection.  This unexpected separation of 
the low-level center, apparently due to the northerly shear, implies 
that there has been no increase of intensity since yesterday.  The 
initial wind speed is held at 45 kt and given the current 
appearance of the system, this may even be a generous intensity 
estimate.

Celia has taken a northwestward jog over the past 6 to 12 hours.  
This is potentially due to the sheared vortex structure.  The storm 
is expected to become more vertically coupled and resume a 
west-northwestward track beginning later today.  The longer-term 
motion should be governed by the mid-level high pressure system and 
associated ridge to the north and northeast of Celia.  The new NHC 
track forecast is shifted slightly northward on a account of the 
recent more northward movement of the cyclone.  This is in close 
agreement with the model consensus. 

The global dynamical models forecast some decrease in the 
vertical wind shear, which should allow for gradual intensification 
of the storm.  However, global models do maintain a moderate 
level of shear and this, along with cooler SSTs within the 
next day or two, could limit strengthening.  The official intensity 
forecast is a little above most of the model guidance.
