A small wildfire swept through a US mobile home park, leaving dozens of homes in ashes, the latest in a series of explosive blazes propelled by gusts that have torn through northern California mountains and forests.

The drought-parched region was expected to see red flag warnings for dangerously high winds and hot, dry weather through to Thursday.
