The wider storm

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.

Began near Carnadero (36.9805, -121.5580).
