Short-lived Tropical Depression Six-E developed from a strong tropical wave
that emerged off the west coast of Africa on 5 July. The wave moved
westward but it was not until the 26 Ih that the convective activity and
the surface circulation became organized in the eastern North Pacific,
nearly 1000 n mi west-southwest of the southern tip of Baja California and
about 360 n mi southwest of Tropical Depression Calvin. The system was then
upgraded to tropical depression status based on a 32-knot wind speed from
microwave imagery data. The depression moved toward the west-northwest and
encountered strong vertical wind-shear. After a few convective bursts, it
became a swirl of low clouds which gradually dissipated on 28 July. The
best track of Tropical Depression
Six-E is indicated in Table 1.
