Tropical Depression Celia Discussion Number  18
NWS National Hurricane Center Miami FL       EP032022
1000 PM CDT Mon Jun 20 2022
 
The depression has become better organized based on geostationary 
and microwave satellite imagery.  The center is embedded in the 
eastern side of a growing area of deep convection.  However, 
subjective satellite estimates still support an intensity at 30 kt 
and therefore, the initial intensity is set to that value.

Despite moderate east-northeasterly shear, the depression is 
expected to gradually re-strengthen in the next day or so.  Celia 
will likely continue to intensify in the following few days, in part 
due to the cyclone moving over warm waters in a low-or-moderate 
shear environment.  At the end of the forecast period, 
intensification will likely halt as the storm encounters cooler 
waters.  The official intensity forecast is very similar to the 
previous one and represents a compromise between the higher 
dynamical hurricane models and lower global model intensities.

Celia continues westward (270/11 kt) due to the steering flow of a 
mid-level ridge to its north, and this motion should persist for 
another day or so.  The system is expected to turn west-northwest 
and eventually northwestward as it rounds the southwest side of the 
ridge.  There is a fair bit of model disagreement this cycle in both 
cross-track and along-track storm positions.  This is possibly due 
to a wide variety of forecast model tropical cyclone vortex depths 
which experience very different environmental steering flows.  The 
NHC track forecast lies to the north of the consensus aids, a little 
closer to the global models, and is slightly faster than the 
previous forecast.  The large spread in model guidance makes this 
track forecast more uncertain than average.
