This depression formed from a tropical wave that was tracked from the coast
of Africa on 20 June. The system was accompanied by a surge in the
lower-tropospheric flow, as evidenced by upper-air data over the Caribbean
Sea. As the wave moved into the extreme western Caribbean on 30 June, a
broad area of lower- to mid-tropospheric cyclonic turning was noted. The
system moved over the Yucatan peninsula on 1 July. Surface observations
suggested that a weak surface low moved from Yucatan into the Bay of
Campeche early on 2 July. Later that day, deep convection became more
organized over the extreme southwest Gulf of Mexico, and reports from a
ship, call sign 9VBK, of northwesterly winds of 20-25 knots about 60 n mi
west-southwest of the estimated center, indicates that a tropical depression
had formed by 1800 UTC 2 July (Table 1 and Fig. 1). Around 0400 UTC 3 July,
the center of the depression crossed the coast of Mexico about 35 n mi
south-southeast of Tuxpan. A few hours later, the cyclone weakened to
dissipation over the mountains of Mexico. Reported rainfall totals (24 hr)
ranged from 105 to 317.3 mm (4.13 to 12.49 in). There were no known
casualties or damages.
