Track of TS 09E

At 8:00 PM PDT (0300 UTC) the center of Tropical Storm Hilary (09E) was located near latitude 14.4 north, longitude 97.2 west.

Hilary is moving toward the west-northwest near 7 mph (11 km/h) and this general motion is expected to continue during the next 24 to 48 hours.

On the forecast track the core of Hilary will continue to move parallel to the southwest coast of Mexico but any deviation to the north of the track could bring stronger winds to the coast.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Strengthening is forecast during the next 48 hours and Hilary is expected to become a hurricane late tomorrow. Tropical storm force winds extend outward up to 50 miles (85 km) from the center. Estimated minimum central pressure is 1000 mb (29.53 inches).

Hazards affecting land include wind and rainfall. Heavy squalls are probably occurring along portions of the southern coast of Mexico already. However, winds of tropical storm force should begin to affect a portion of the coast soon, and should spread westward along the tropical storm warning area during the next 24 to 36 hours. Hilary is expected to produce rainfall amounts of 3 to 5 inches across portions of southern Mexico with isolated amounts of 10 inches possible.
