Heavy rain unleashes mud, debris flows in Northern California areas burned by wildfire

Bomb cyclone. Rivers of rain. Emergency response officials have been bracing all week for the worst days of the storm — and it finally arrived late Saturday evening. By Sunday morning, the torrential rainfall had shut down at least one critical highway as mud, rocks and unshackled debris flushed down denuded hillsides.

Flash flood warnings for both the Dixie and Caldor regions were in effect until 3 a.m. Monday. More than a foot of rain could fall in the Sierra Nevada, with up to 3 feet of snow possible at higher elevations through Tuesday.

In Southern California there were scattered showers through the weekend, with more on the way Monday.

Search warrant reveals new details in Alec Baldwin prop gun shooting; Experts predict the legal fallout

Actor Alec Baldwin was practicing removing a revolver from its holster and aiming toward the camera during rehearsal for the movie “Rust” when director Joel Souza heard “what sounded like a whip and then a loud pop,” according to a search warrant obtained by the Los Angeles Times on Sunday night that also provided grim new details about the final minutes of cinematographer Halyna Hutchins’ life.

In the newly released document Souza said someone identified the weapon as a “cold gun,” meaning it did not have any live rounds. But instead the gun discharged, according to a Santa Fe County, N.M., sheriff’s detective’s affidavit used to obtain a search warrant.

The shooting death could have far-reaching legal ramifications, experts said — not only for the companies involved but also for individuals, including Baldwin.

FROM THE ARCHIVES

On Oct. 25, 1928, Edward Doheny, an oilman from California, paid $100,000 to Albert B. Fall, who served as secretary of the Interior in President Harding’s Cabinet. Doheny wanted wanted Fall to grant his firm a valuable oil lease in the Elk Hills naval oil reserve in California.

ONLY IN CALIFORNIA

Deaths from drug overdoses have surged during the pandemic, claiming more than 90,000 lives last year across the country, according to federal data. As the numbers have soared, many experts, advocates and lawmakers have promoted an idea still fresh to the United States: giving people a safe place to inject drugs under supervision.

In California, it would be the most dramatic step to date for government and health officials in pursuing the philosophy of harm reduction, which seeks pragmatic ways to reduce the harmful effects of drug use. The idea was shot down three years ago by Gov. Jerry Brown, who vetoed a bill to try out such sites in San Francisco and said that “enabling illegal and destructive drug use will never work.”

Now state Sen. Scott Wiener (D-San Francisco) and other lawmakers are pushing to allow San Francisco, Oakland and the city and county of Los Angeles to approve entities to run such programs.
