Brief Information About
Tropical Depression Six-E
26 - 28 July, 1999

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.
