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.
