A tropical wave that moved westward from the coast of Africa on
23 July reached the eastern Pacific on the 29th. The
wave continued westward with little development until 3 August,
when convection started to increase. After additional slow
organization, the system became a tropical depression near 0000 UTC
6 August about 785 n mi southwest of the southern tip of Baja
California (Table 1). Development was then halted by southwesterly
vertical shear that eventually destroyed the system. The cyclone
moved northwestward for two days before it dissipated early on the
8th about 930 n mi west-southwest of the southern tip of
the Baja California peninsula.
