The US Pacific Coast's most ferocious storm in years has moved south, bringing hurricane force winds to southern California - one day after claiming two lives in Oregon.
According to reports, a homeless man and a young boy were killed by falling trees.
Severe flooding, mudslides and high winds - some gusting up to 225 kilometres an hour - wreaked havoc as the storm swept down California's coastline, buffeting Los Angeles and San Diego.
More than 220,000 people were without power as the rain and wind hit, the BBC reported yesterday.
The flooding closed at least two major motorways, delayed public transport, cancelled at least 240 flights and shut ferry services.
The power cuts caused by the storm were widespread, reaching as far north as Canada as well as the state of Washington.
"It's a two-pronged punch - it's wind and rain," National Weather Service forecaster Diana Henderson said.
"Once the ground gets saturated and the winds are howling, there's a bigger chance of trees going down on power lines."
The Los Angeles Times reported that the storm had trapped people inside their homes and cars.
While rain was needed in the drought-hit state, mudslides were a concern - and officials issued evacuation orders in some areas prone to floods and mud flows.
The storm led to rare weather-related school closures for students in San Francisco, Oakland, Berkeley, and Santa Cruz County.
