Atmospheric River Moving Through the Pacific Northwest 

A powerful atmospheric river, a narrow band of moisture that can bring torrential rain and flooding, is set to hit the Pacific Northwest this weekend.

This storm is expected to be the most significant weather event of the winter season so far, with widespread impacts across Washington state and British Columbia, Canada.

Heavy Rain and Flooding 

The primary concern with this atmospheric river is the potential for excessive rainfall, which could lead to widespread flooding. Coastal regions, especially in Vancouver and its surrounding areas, are expected to bear the brunt of the storm.

Rainfall totals could exceed 10 inches in some areas, overwhelming storm drains and causing flooding in low-lying regions.

Mudslides and Landslides 

The heavy rain could also trigger mudslides and landslides, particularly in hilly or mountainous terrain. Areas prone to these hazards should be especially vigilant.

Snowfall at Higher Elevations 

While the lowlands will experience heavy rain, higher elevations in the region could see significant snowfall. Snow levels are expected to fluctuate throughout the weekend, but snowfall totals could reach several feet in some areas.

This could lead to additional flooding as snow melts and runs off into waterways. 

Strong Winds and Rough Seas 

The storm will also bring strong winds, which could create hazardous conditions for boating and other outdoor activities. Rough seas are expected in the Pacific Ocean and surrounding waters.
