Tropical storm Sergio is some 290 kilometers (180 miles) away from Punta Abreojos on the western coast of Baja California Sur and is approaching at a speed of 37 kilometers per hour, Mexico's National Meteorological Service (SMN) said Thursday.

In SMN's 10 pm forecast, it reported that Sergio is expected to make landfall as a tropical storm with sustained winds up to 95km/h and gusts up to 110 km/h and would reach Guaymas Sonora as tropical depression.

At 07.00h on Oct. 12, the storm is expected to make landfall, 55 kilometers east of Punta Abreojos and around 19.00h it is expected to touch the Mexican state Sonora, 245 kilometers northeast of the port of Guaymas.

Sergio is expected to cause intense storms in Baja California and Baja California Sur and heavy rainfall in Sonora and Chihuahua states.

The Baja California Sur government declared an alert for Sergio and schools will be closed on Friday while 27 shelters are in operation to help residents of the affected areas.

Sergio turned into a tropical storm on Sep. 29 in the Mexican Pacific region and became a hurricane, reaching category 4 on the Saffir-Simpson scale on Oct. 3, but was later downgraded as it headed towards land.
