Post-Tropical Cyclone Georgette Discussion Number  30

Convection associated with Georgette dissipated this morning, and
only a few isolated showers have development since that time.  The
small circulation now consists of a swirl of low- to mid-level
clouds.  Although small bursts of convection could still develop in
associated with the system over the next day or so, it has not had
appreciable organized deep convection in quite some time.
Therefore, it no longer meets the definition of a tropical cyclone,
and this will be the final NHC advisory on Georgette.  The initial
intensity has been reduced to 25 kt.  Weakening should continue
over the next 24 to 36 hours as the systems moves over SSTs below 
26C and into a dry mid-level environment.  The low is expected to 
become an open trough in 36 to 48 hours as indicated by the global 
model guidance. 

The cyclone is now moving northward at about 7 kt. A low-level 
ridge is forecast to build to the north of the system, and this 
should cause the low to turn westward on Thursday.  A general 
westward motion should then continue until dissipate occurs. The 
new NHC track prediction is a little north of the previous 
advisory to be in better agreement with the latest dynamical model 
guidance envelope.
