Weather Channel —
A parade of Pacific storm systems will bring soaking rain and some mountain snow to drought-stricken California and the West Coast, but could also trigger dangerous debris flows over recent areas burned by wildfires.
Last weekend, a weak Pacific frontal system ended a record-long dry streak in Sacramento, and shut down Interstate 80 for a time due to snow and wrecks in the Sierra.
It was a sample of what’s ahead.
A persistent southward plunge of the jet stream over the eastern Pacific Ocean will steer storm systems toward the West Coast into next week.
