Heavy rainfall and flooding began Saturday ahead of the storm’s expected Sunday crossing into the southwestern U.S., where it is expected to dump up to 10 inches of rain in southern California and southern Nevada.
“This does not lessen the threat, especially the flood threat,” said Jamie Rhome, the U.S. National Hurricane Center’s deputy director, during a Saturday briefing to announce the storm’s downgraded status. “Don’t let the weakening trend and the intensity lower your guard.”
Meteorologists also expect the storm to churn up “life-threatening” surf conditions and rip currents — including towering waves up to 40 feet high — along Mexico’s Pacific coast. Dozens sought refuge at storm shelters in the twin resorts of Los Cabos, at the southern tip of the Baja peninsula, and firefighters used an inflatable boat to rescue a family in San Jose del Cabo after the resort was hit by driving rain and wind.
In Tijuana, Rafael Carrillo voiced the fear that was at the back of everyone’s mind in the border city of 1.9 million, particularly residents who live in homes that cling precariously to steep hillsides.
”If you hear noises, or the ground cracking, it is important for you to check it and get out as fast as possible, because the ground can weaken and your home could collapse,” said Carrillo, head of the Tijuana fire department.
That city ordered all beaches closed Saturday, and set up a half-dozen storm shelters at sports complexes and government offices.
Mexico’s Navy evacuated 850 people from islands off the Baja coast, and deployed almost 3,000 troops for emergency operations. In La Paz, the picturesque capital of Baja California Sur state on the Sea of Cortez, police patrolled closed beaches to keep swimmers out of the whipped-up surf.
In the U.S., the Miami-based hurricane center issued tropical storm and potential flood warnings for Southern California from the Pacific coast to interior mountains and deserts. The San Bernardino County sheriff on Saturday issued evacuation warnings for several mountain and foothill communities ahead of the storm.
And an evacuation advisory for the tourist destination of Santa Catalina Island, 23 miles off the Southern California coast, urged residents and beachgoers to leave, while authorities in Los Angeles scrambled to get the homeless off the streets and into shelters.
Across the region, municipalities ran out of free sandbags and grocery shelves emptied out as residents stockpiled supplies. The U.S. National Park Service closed California’s Joshua Tree National Park and Mojave National Preserve to keep visitors from becoming stranded amid flooding.
Major League Baseball rescheduled three Sunday games in Southern California, moving them to Saturday as part of split doubleheaders, and SpaceX delayed the launch of a satellite-carrying rocket from a base on California’s central coast until at least Monday. The company said conditions in the Pacific could make it difficult for a ship to recover the rocket booster.
President Joe Biden said Friday the Federal Emergency Management Agency had pre-positioned staff and supplies in the region. “I urge everyone, everyone in the path of this storm, to take precautions and listen to the guidance of state and local officials,” he said.
Hilary on Friday had rapidly grown into an exceedingly dangerous Category 4 Major hurricane for a time with top sustained winds of 145 mph at its peak. Its maximum sustained winds initially dropped to 115 mph earlier Saturday as a Category 3 storm, before further weakening to 110 mph — making it a Category 2.
By midafternoon Saturday, it was still 640 miles south-southeast of San Diego, California. Moving north-northwest at 17 mph, the storm was expected to turn more toward the north and pick up speed.
Forecasters said the storm was swirling off one of the westernmost spurs on Mexico’s southern Baja peninsula. The hurricane was expected to brush past Punta Eugenia on that coast before making a nighttime landfall along a sparsely populated area of the peninsula about 200 miles south of the Pacific port city of Ensenada.
Hilary is likely then to rake northward all the way up the peninsula and into Tijuana, before heading to the U.S. in its historic path.
