Power Outage in Alviso, CA

Sub-tropical jet stream aided in advecting sub-tropical moisture plume from over the Central Pacific into the California Coast starting March 9th through the 11th. This led to widespread flooding around the CWA, numerous landslides, sharp rises in rivers in Monterey County, and widespread power outages from downed trees and powerlines due to strong, gusty winds. Widespread wind gusts 45 to 55 mph were reported on the evening of the 9th and into the early hours of the 10th. Heavy rains during the same time flooded numerous streams, creeks, rivers, and roads. 4-7 inches of rain fell across the Santa Cruz Mountains while 5-10 inches of rain fell on the Santa Lucia Mountains.

A plume of moisture from the tropical Pacific brought an Atmospheric River to the Bay Area January 26th-29th. This system generated heavy rain rates causing flooding and debris flows over area burn scars as well as 15 to 20 inches of rain in the Santa Lucia Mountains. Mudflows near the River Fire burn scar in Monterey County caused damage to homes, covered roadways, and trapped animals at local ranches. Debris flows near the Dolan Fire burn scar caused an entire section of Highway 1 near Rat Creek to collapse into the Pacific Ocean. This was an unusually cold system for an Atmospheric River resulting in lower snow levels and allowing for accumulating snow as low as 1300 feet in elevation. Additionally, strong south to southeast winds gusted to 60-70 mph across area peaks with Mt Diablo reaching 80 mph. Valley locations were gusting up to 40 mph. Numerous trees fell across the region including into homes and onto cars. Multiple power outages were also reported. It is estimated that the storm caused millions of dollars in damage across Santa Cruz County https://www.ksbw.com/article/emergency-declaration-made-in-santa-cruz-county-for-millions-in-damages/35400060.
