Tropical Storm Celia Discussion Number  40
NWS National Hurricane Center Miami FL       EP032022
900 AM MDT Sun Jun 26 2022

This morning's satellite presentation shows very little change in
Celia's cloud pattern.  However, the cloud tops associated with the 
deep convection are beginning to warm.  The latest AMSR2 microwave 
revealed a symmetric cyclone with an eye-like feature in the 
low-frequency band.  Therefore, the initial intensity is 
conservatively held at 45 kt and is supported by a blend of the 
subjective and objective satellite intensity estimates.

Celia should gradually weaken while it moves into a stable and 
dry surrounding atmosphere, and over cooler oceanic surface 
temperatures. Accordingly, Celia is expected to degenerate into a 
post-tropical cyclone on Monday and dissipate toward the end of the 
week, and this scenario is in agreement with the latest statistical 
and dynamical intensity guidance.

Celia's initial motion is estimated to be west-northwestward, or 
285/6 kt, just a little bit to the left of the previous advisory 
motion.  The forecast track philosophy remains the same.  A 
mid-tropospheric ridge anchored over the eastern North Pacific 
should steer the cyclone on a continued west-northwestward course 
through the forecast period.  The official NHC forecast is based on 
the various tightly clustered consensus aids.
