All Evacuation Orders Lifted In San Mateo County

SAN MATEO COUNTY, CA — Cal Fire lifted evacuation orders in parts of the CZU Lightning Complex burn area in San Mateo County on Monday morning, as the flash flood watch and wind advisory for the area expired.

Evacuation orders were put in place for the following areas on Sunday ahead of the storm that downed trees and closed roads around the Bay Area:

• South Coast Zone SMC-E019, which includes Año Nuevo State Park, Whitehouse Canyon Road and areas south of Gazos Creek Road east of Highway 1.
• South Coast Zone SMC-E038, which includes Butano State Park and the community of Barranca Knolls, west of Cloverdale Road.
• The communities of Loma Mar and Dearborn Park in Zone SMC-E018.
• The Community of Butano Canyon in Zone SMC-E098

An evacuation point set up at the Ted Adcock Center in Half Moon Bay was closed Monday. Officials warned that people should still continue to use caution when driving due to potential water accumulation and downed trees and branches.

It's "been a memorable past 24 hours for the Bay Area as the long-talked-about atmospheric river rolled through the region," the National Weather Service said before dawn Monday. "We literally have gone from fire/drought conditions to flooding in one storm cycle."

Atmospheric rivers are "relatively long, narrow regions in the atmosphere — like rivers in the sky," according to the National Oceanic and Atmospheric Administration. A bomb cyclone occurs when a storm experiences bombogenesis, meaning it rapidly intensifies over a 24-hour period, according to NOAA.
