On August 17 a tropical wave, probably from the same wave from which Tropical Depression Ten had developed from earlier in the month, began to organize in the central Caribbean. Convection steadily increased as it moved to the Yucatán Peninsula. The system then weakened while overland, and by the time when it entered the southweatern Gulf of Mexico on August 21 it hardly had any convection. However early in the morning of August 22 under highly favorable upper-level conditions, convection quickly increased and the system became Tropical Depression Eleven about 110 miles (175 km) east of Veracruz, Mexico. The depression quickly strengthened as it moved to the west, becoming Tropical Storm Jose just six hours later after forming.
