At 5:00 p.m. EDT on Saturday the center of Tropical Storm Kevin was located at latitude 15.8°N and longitude 106.8°W which put it about 530 miles (855 km) south-southeast of the southern tip of Baja California. Kevin was moving toward the west at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).

More thunderstorms developed near the center of a low pressure system southwest of Mexico on Saturday afternoon and the National Hurricane Center designated the system as Tropical Storm Kevin. The circulation around Kevin exhibited more organization as the day progressed. As mentioned previously, more thunderstorms formed near the center of circulation. More thunderstorms also developed in bands revolving around the center of Tropical Storm Kevin. Storm near the center began to generate upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 45 miles in the northern half of Kevin’s circulation. Winds in the southern half of the circulation were blowing at less than tropical storm force.

Tropical Storm Kevin will move through an environment favorable for intensification during the next 36 hours. Kevin will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Kevin will continue to intensify and it could strengthen into a hurricane by Monday.

Tropical Storm Kevin will move south of a ridge of high pressure that extends from the Gulf of Mexico to the Eastern North Pacific Ocean. The ridge will steer Kevin toward the west-northwest during the next few days. On its anticipated track Tropical Storm Kevin will remain south of Baja California.
