Mexico ? A strengthening Hurricane Jimena roared toward Mexico’s Baja California peninsula, where residents stocked up on food Sunday and authorities set up shelters, anticipating landfall in the coming days.

Mexico issued a hurricane watch for the resort-dotted southern portion of Baja, meaning hurricane conditions are possible within 36 hours.

Jimena, a dangerous Category 4 storm, could rake southern Baja California by Tuesday evening, forecasters said,

At least 10,000 families will be evacuated from potential flood zones, said Francisco Cota, the local director of Civil Protection. He said 60 shelters would be set up.

On Sunday night, Jimena had maximum sustained winds near 145 mph and was moving west northwest at 7 mph.

It was centered about 445 miles southeast of Cabo San Lucas and 255 miles south of Cabo Corrientes, a coastal town in the western state of Jalisco.
