Due to the two-year drought in California, emergency authorities do not expect the river to flood. However, there was growing concern about the landslides that broke out in the Diablo Range from Santa Cruz, Sonoma, Napa, Big Sur, Milpitas to Gilroy.

“It’s not enough to end the drought,” said Tony Estremera, chairman of the Santa Clara Valley body of water. “We must continue to save water as much as possible.”

This year, rain has almost ended the risk of fire in some areas. From Monday to Friday afternoon, Mount Tamalpais in Marin County received an astonishing 10.3-inch rain. Mount Diablo in Contra Costa County was 4.51 inches and Ben Lomond in the Santa Cruz Mountains was 3.1 inches.

In urban areas, San Francisco received 1.81 inches from Monday, doubling the historical average for October. Oakland was 1.19 inches and San Jose, which was limited by the “rainshadow” effect of the Santa Cruz Mountains, was 0.28 inches.
