Tropical Depression Ten formed over the Yucatan Channel on Saturday afternoon. At 5:00 p.m. EDT on Saturday the center of Tropical Depression Ten was located at latitude 21.1°N and longitude 86.1°W which put it about 65 miles (105 km) northeast of Cozumel. The tropical depression was stationary. The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1006 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Tulum to Rio Lagartos, Mexico. The Tropical Storm Warning included Cozumel. A Tropical Storm Warning was also in effect for the Cuban Provinces of Pinar del Rio and Isle of Youth.

A low pressure system over the Yucatan Peninsula exhibited more organization on Saturday afternoon and the U.S. National Hurricane Center designated it as Tropical Depression Ten. The circulation around Tropical Depression Ten was still organizing. There was a weak center of circulation at the surface. Radar images from western Cuba indicated that there was a stronger circulation in the middle troposphere. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center started to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Ten will be in an environment mostly favorable for intensification during the next 24 hours. The tropical depression will be over water where the Sea Surface Temperatures are near 30°C. It will be under an upper level ridge over the Yucatan Channel. The winds are weak in the upper level ridge and there will be little vertical wind shear. However, much of the air moving around the western side of Tropical Depression Ten will pass over the northeastern Yucatan Peninsula. Some of the air in the western side of the tropical depression will pass over western Cuba. The flow of air over land will inhibit intensification, but it probably will not prevent intensification. Tropical Depression Ten could intensify slowly on Sunday.

Tropical Depression Ten will be in a region where the steering currents are weak during the next 24 hours. Tropical Depression Ten may not move much on Sunday. A high pressure system over the western Atlantic Ocean will start to steer the tropical depression toward the north early next week. Tropical Depression Ten is likely to strengthen when it moves over the eastern Gulf of Mexico.

Tropical Depression Ten will drop heavy rain over parts of the northeastern Yucatan Peninsula and western Cuba. Heavy rain could cause flash floods in some locations.

Elsewhere, Hurricane Franklin strengthened over the Atlantic Ocean south-southwest of Bermuda. At 5:00 p.m. EDT on Saturday the center of Hurricane Franklin was located at latitude 23.8°N and longitude 67.5°W which put it about 610 miles (980 km) south-southwest of Bermuda. Franklin was moving toward the north-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 982 mb.
