This discussion is a hoot. :)

Hurricane Epsilon Discussion Number 21
Statement as of 10:00 am EST on December 04, 2005

 
after a slight weakening overnight...morning satellite images
indicate that Epsilon has restrengthened. The eye has become more
symmetric and the ring of convection is stronger than yesterday.
T-numbers from TAFB and SAB are 4.5 on the Dvorak scale and on this
basis...the initial intensity is increased to 75 knots. There are
no clear reasons...and I am not going to make one up...to explain
the recent strengthening of Epsilon and I am just describing the
facts. However...I still have to make an intensity forecast and the
best bet at this time is to predict weakening due to cold water
...High shear and dry air.

 
Epsilon is moving eastward at 10 knots...running ahead of a strong
mid-latitude trough. But soon...according to the global
models...the cyclone will be trapped south of a developing ridge
which eventually force Epsilon southward and then southwestward.
There is fairly good guidance agreement in showing this motion.
Although Epsilon will encounter warmer waters once it moves toward
the southwest. However...the upper level winds are expected to be
highly unfavorable and Epsilon will likely become a remnant low. I
heard that before about Epsilon...haven't you?
