Strong, gusty winds peaking at 47 mph at Modesto Airport brought down hundreds of trees, large tree branches, and power lines resulting in power outages in Stanislaus County. Falling trees also badly damaged numerous cars and houses.

The wider storm

The remnants of Super Typhoon Melor from the western Pacific Ocean combined with a Canadian upper level low pressure system to form a strong storm over Northern California. Numerous trees and large branches were knocked down, causing damage to cars, homes, and power lines which resulted in the loss of power to thousands of customers. Heavy rain caused minor flooding on roads and in small streams.
