Tropical Storm Celia Discussion Number  39

300 AM MDT Sun Jun 26 2022

Geostationary satellite imagery shows increased convection 
on the western and southern sides of Celia's circulation.  
However, as the system passed just south of the island of Socorro 
yesterday, a weather station did not even measure any sustained 
tropical-force-winds.  Subjective and objective satellite intensity 
estimates range between 40 and 55 kt.  The initial intensity has 
been lowered to 45 kt to reflect a compromise between all of the 
estimates and observations.  Celia will move into increasingly 
unfavorable environmental conditions, with sea surface temperatures 
below 25 C and a dry and stable airmass.  Therefore, continued 
weakening is expected.  The official forecast predicts the system 
will be post-tropical by 36 h and a remnant low in two days.  This 
intensity forecast is lower than most of the model guidance.

Celia is moving west-northwest at about 9 kt, steered by a mid-level 
ridge.  As the system loses convection and becomes a shallow remnant 
low, it is expected to turn westward within the low-level trade 
winds.  The NHC track forecast lies on the southern half of the 
guidance envelope partially due to the intensity forecast, assuming 
a quicker westward turn for a weaker cyclone.
