Winds, rain & snow, oh my! This is the time of year for storminess in the Northwest, but rarely do we see this much weather in such a short period of time.

Multiple storm systems are churning and building strength over the Pacific Ocean and their predicted effects have been dynamically changing over the past 48 hours. I will break up the storm’s impacts into two sections.

STORM 1: Monday, November 16:


The center of Storm 1 is actually striking hundreds of miles away in British Columbia. The front of the storm extends over a thousand miles in the Pacific Ocean, this storm is BIG.

STORM 1 Impacts: 1:00pm – 4:00am Tuesday. 

  • Heavy rain to the Olympic foothills and rivers. [Flood Watch]
  • Heavy snow (up to 2 feet) over the tops of the Olympic and Cascade mountains. [Winter Storm Warning]
  • High winds to the northern Puget Sound and Washington/Oregon coasts, as well as strong gusts to the northern Olympic peaks. [Wind Advisory]

Seattle, Burien, and Tacoma are expected to get heavy rain at times (most of it will be blocked by the Olympic Mountains), and moderate winds gusting up to 35mph.

STORM 2: Tuesday, November 17:


Now this is a sneaky storm. This storm is also landing hundreds of miles north into Canada. The potential damage won’t come from it’s strength or track.

This storm’s force will come from a “trifecta interaction” between the low pressure of the storm itself, a huge hill of high pressure pressing down on the Pacific ocean, and another strong storm further out to sea. This combination will create a “squeezing” effect of the winds into Washington.

Soils will be packed full of water accumulated from the last few storms we’ve had. Consequently, Trees may be more likely to topple in high winds. Be sure to prepare your power outage supplies.

It’s that time of year! I love storms.
