The West Coast is bracing for heavy precipitation as this massive Pacific storm system ushers deep #AtmosphericRiver moisture onshore over the next few days. Heavy coastal rains and mountain snow will impact millions from southern Oregon to southern California. #ORwx #CAwx

The west coast is bracing for another big wind and rain event as this massive Pacific Low churns offshore. #GOESWest water vapor imagery shows a wide fire hose of moisture splaying outward as the storm advances. #WAwx #ORwx #CAwx #BCstorm

#GOESWest is tracking the next Pacific Low coming onshore the U.S. West Coast. Note also the thin rope cloud rolling southeastward ahead of this powerful system. #WAwx #ORwx #CAwx

Here's a look at the flow of Pacific moisture feeding into recent West Coast weather systems dumping snow in the Cascades and widespread rains at lower elevations for #WAwx, #ORwx and #CAwx. Fortunately, High pressure is forecast to bring a prolonged dry period to the region. https://t.co/0pWxz8LeG0

Precipitation returns to the U.S. West Coast this weekend as a large Low pressure system ushers Pacific moisture onshore. This view via #GOESWest water vapor imagery. Heavy rain will drench coastal areas and heavy snow will fall in the mountains. #WAwx #ORwx #CAwx https://t.co/IhIkAizPSG

For western OR/WA expect:
🍃Strong winds at the coast, gusty winds inland
🌧️Moderate to heavy rain 🌬️
❄️Mountain snowfall
