Communities are still reeling from last week’s lashing as weather service warns of more ‘lengthy period of heavy rain’

A second atmospheric river-fueled storm is lashing California, threatening dangerous extreme weather in the state.

The National Weather Service warned continuous rainfall would hit over a 48-hour period in some already sodden areas across the state, including the central coast, the Los Angeles basin and in the mountain ranges.

“This heavy rainfall will bring the threat for life-threatening flash, urban, and river flooding as well as debris flows and mudslides,” the agency reported in a Sunday morning update.

Heavy snow and strong winds are expected to create impossible travel conditions in the mountains and destructive high surf along the coast.

The National Weather Service issued its first ever warning of hurricane force winds for the San Francisco area in northern California, with winds strong enough to cause flight cancellations and diversions out of San Francisco airport while, further south, the federal service gave a rare “high risk” of flash flooding warning for Los Angeles.
