Tropical Depression TEN-E


Tropical Depression Ten-E Discussion Number   1

I thought there was no more room for another cyclone in the eastern
Pacific basin, but nature managed to produce another one. The
disturbance that NHC has been monitoring for several days has
finally developed enough circulation and convection to be classified
as a tropical depression, the sixth cyclone that has formed in the
month of July.

The center is located on the northern edge of a circular mass of
deep convection and, based of an average of Dvorak numbers, it is
being assigned an initial intensity of 30 kt.  The depression is in
between TS Greg and TD 9-E, and the environment is not ideal for
strengthening. However, most of the global models show a decrease
of the shear in the next few days, and this will allow some

The depression is trapped south of a subtropical ridge and is moving
toward the west at about 6 kt.  The nose of the ridge is forecast to
amplify westward, and this flow pattern will likely force the
cyclone on a slow west and then west-southwest track during the next
five days. Most of the guidance agree with this solution, but one
must use caution since there could be some interaction with Tropical
Depression Nine-E which increases the forecast uncertainty.
