Tropical Storm Celia Discussion Number  33

Celia has the appearance of becoming better organized, with
subjective and objective satellite intensity estimates of
T4.0 all suggesting it's at hurricane strength.  However, two
recent scatterometer passes only showed winds as high as 35-40 kt,
so any strengthening of the wind field is apparently lagging the
improved convective structure.  Because of this large discrepancy
in estimates, the initial intensity is held at 55 kt.  The
scatterometer data also indicate that Celia is asymmetric, with no
tropical-storm-force winds on the west side.
 
Celia's speed has slowed further, and the initial motion estimate 
is 285/5 kt.  This is about the slowest Celia is expected to move, 
and its forward speed is forecast to gradually increase over the 
next five days as the ridge to the north strengthens and expands 
westward.  There are no significant changes to the track forecast 
reasoning on this cycle, and the updated NHC track prediction is 
basically an update of the morning forecast.

Celia still has a small window of time for the wind field to 
strengthen and catch up to the satellite presentation, and the NHC 
forecast continues to show it becoming a hurricane in the next 12 
to 24 hours.  This forecast closely follows the HCCA consensus aid. 
However, cooler waters ahead of the storm are expected to induce 
weakening after 36 hours, and Celia is likely to become 
post-tropical by day 4 when it loses its deep convection.
