A small swirl of low clouds developed along the Intertropical Convergence Zone well to the south-southwest of Baja California on 30 September. The swirl moved westward with little development until 2 October when it started to generate convection. Satellite intensity estimates indicate the system became a tropical depression near 0000 UTC 3 October about 800 n mi southwest of the southern tip of Baja California (Table 1). The convection did not persist as the system moved westward to west-northwestward, and the cyclone dissipated early on 4 October about 900 n mi southwest of the southern tip of Baja California. The remnant low cloud swirl continued westward for another 24-36 h before dissipating completely.
