Hurricane Hilary roared toward Mexico’s Baja California peninsula as a downgraded but still dangerous Category 2 hurricane that’s likely to bring “catastrophic” flooding to the region and cross into the southwest US as a tropical storm.
Meteorologists warned that despite the hurricane’s weakening, the storm’s speed had accelerated Saturday and remained treacherous. One person drowned Saturday in Mexico’s town of Santa Rosalia, along the peninsula’s eastern coast, when their vehicle was swept away in an overflowing stream. Rescue workers managed to rescue four other people, according to Edith Aguilar Villavicencio, the mayor of Mulege township.
While it was not immediately clear whether officials consider the fatality to be related to the hurricane, footage posted by local officials showed torrents of water coursing through the town’s streets.
Forecasters said the storm is still expected to enter the history books as the first tropical storm to hit Southern California in 84 years, and bring along flash floods, mudslides, isolated tornadoes, high winds and widespread power outages.
“I don’t think any of us — I know me particularly — never thought I’d be standing here talking about a hurricane or a tropical storm,” said Janice Hahn, chair of the Los Angeles County Board of Supervisors.
The US National Hurricane Center issued tropical storm and potential flood warnings for a wide swath of 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.
“This is being labelled as historic, life-threatening and potentially catastrophic rainfall for Southern California and a good chunk of the desert Southwest in general,” said John Cangialosi, a senior hurricane specialist at the National Hurricane Center. “That is because we could see about a year’s worth of rain from this event for those regions.”
Mexico’s Navy evacuated 850 people from islands off the Baja coast and deployed almost 3000 troops for emergency operations. In Nevada, Governor Joe Lombardo activated 100 Nevada National Guardsmen to provide support in areas that could be impacted by flash floods this weekend.
After rapidly gaining power on Friday, Hilary slowed by Saturday but remained a major Category 3 hurricane with maximum sustained winds of 185km/h, down from 230km/h at its peak.
By mid-day Saturday, the storm was centred about 570km/h south-southeast of Punta Eugenia, one of the westernmost spurs on the southern Baja peninsula. The hurricane was expected to brush past Punta Eugenia before making landfall along a sparsely populated area of the Baja peninsula at a point about 330km south of the Pacific port city of Ensenada.
It was still 1145km south-southeast of San Diego, California. It was moving north-northwest at 26km/h and was expected to turn more towards the north and pick up speed.
It is then expected to continue northward up the peninsula, raising fears that heavy rains could cause dangerous flooding in the border city of Tijuana, where many homes in the city of 1.9 million cling precariously to steep hillsides.
Mayor Montserrat Caballero Ramirez said the city was setting up four shelters in high-risk zones and warning people in those areas.
“We are a vulnerable city, being on one of the most visited borders in the world and because of our landscape,” she said.
Concern was rising in the US, too.
The US National Park Service closed California’s Joshua Tree National Park and Mojave National Preserve to keep visitors from becoming stranded amid flooding. Cities across the region, including in Arizona, were offering sandbags to safeguard properties against floodwaters. Major League Baseball rescheduled three Sunday games in Southern California, moving them to Saturday as part of split doubleheaders.
Deputies with the Los Angeles Sheriff’s Department took to the road to urge homeless people living in riverbeds to seek shelter. Authorities in the city were arranging food, cots and shelters for those who needed them.
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 on Friday that 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.
Officials in Southern California were re-enforcing sand berms, built to protect low-lying coastal communities against winter surf, like in Huntington Beach, which dubs itself as “Surf City USA.”
In nearby Newport Beach, Tanner Atkinson waited in a line of vehicles for free sandbags at a city distribution point.
“I mean a lot of people here are excited because the waves are gonna get pretty heavy,” Atkinson said. “But I mean, it’s gonna be some rain, so usually there’s some flooding and the landslides and things like that.”
About 100 people 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.
Some schools in Cabo San Lucas were being prepared as temporary shelters, and 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. Schools were shut down in five municipalities.
It was increasingly likely that Hilary would reach California on Sunday while still at tropical storm strength, though widespread rain was expected to begin as early as Saturday, the National Weather Service’s San Diego office said.
Hurricane officials said the storm could bring heavy rainfall to the southwestern United States, dumping 8 to 15cm in places, with isolated amounts of up to 25cm in portions of southern California and southern Nevada.
“Two to three inches of rainfall in Southern California is unheard of” for this time of year, said Kristen Corbosiero, a University at Albany atmospheric scientist who specializes in Pacific hurricanes. “That’s a whole summer and fall amount of rain coming in probably six to 12 hours.”
The region could face once-in-a-century rains and there is a good chance Nevada will break its all-time rainfall record, said meteorologist Jeff Masters of Yale Climate Connections and a former government in-flight hurricane meteorologist.
