An Atmospheric River Eyeballs The Pacific Northwest

An elongated, steady stream of moisture commonly referred to as an ‘atmospheric river’ is forecast to arrive at the Pacific Northwest coastline this weekend.

Late this week, the river of moisture across the Pacific was still well out to sea. It will arrive quickly by Saturday night or early Sunday morning.

First up will be Oregon, far southern Washington as well as far northern California on Saturday evening. This will translate to another batch of heavy rain showers and mountain snow showers Saturday night. Another steady stream of moisture will reinforce those rain/snow showers on Sunday and even into Monday for the Pacific Northwest.

As a result of the heavy rain, a flood watch has been issued for southwest Oregon and northwest California. That means there is the potential for river flooding and street flooding. Remember: Turn Around, Don’t Drown! With some snow still left to melt and the incoming rain, flooding will be a possibility across parts of the Northwest.
