California Coastal Damage and El Niño Preparations
Heavy surf breached sand berms in coastal cities such as Long Beach and Newport Beach, partially submerging oceanfront homes. Flood warnings remained in effect for much of the California coastline, from San Diego to the San Francisco Bay area. As the storm moved inland, rockslides temporarily blocked roads, and Las Vegas broke a daily rainfall record on Sunday. The National Weather Service issued a flood watch for much of Utah, including Salt Lake City.
Forecasters warned that Rachel may be a preview of the coming winter, which is expected to feature the strongest El Niño weather pattern on record. This pattern brings hotter-than-average ocean temperatures and is likely to cause record rainfall, explosive surf, and mudslides. In response, California Gov. Gavin Newsom issued an emergency proclamation last month to release resources for infrastructure protection and resident education.
"That means getting flood-fighting supplies into position, bolstering our water infrastructure, and helping communities across the Golden State prepare," Newsom said in a statement.
The state is pre-positioning more than 4 million sandbags, more than 50,000 feet of portable flood barriers, and 400,000 tons of rock for levee repairs. Meanwhile, Hurricane Simon lashed Mexico's Pacific Coast as a Category 4 hurricane over the weekend. Mexican President Claudia Sheinbaum urged residents to stay indoors, noting that precautionary evacuations were ongoing.
