A strong jet stream will bring cold, unstable air from the Gulf of Alaska into Western Washington this week, resulting in lowland rain, mountain snow accumulations of 2-4 feet, and blustery conditions with possible power outages. Snow levels will vary from 500 feet to 3,000 feet, and the new snow is welcome news for ski areas and the region's water supply.

Why it matters

This late winter surge in mountain snow will help cut into the snowpack deficit in the Olympics and Cascades, which was only 35-45% of average earlier this month. The additional snow is critical for the region's water supply, agriculture, power generation, recreation, and fish habitats heading into the drier summer and fall months.

The details

The weather pattern will generate showers in the lowlands, with rain totals ranging from 0.5 to over 2 inches, and plenty of snow in the mountains. Snow levels will vary from as low as 500 feet early in the week to as high as 3,000 feet on Wednesday, before dropping to around 2,000 feet for the rest of the week. Drivers going over the mountain pass highways should anticipate hazardous winter driving conditions, and those heading into the backcountry should monitor avalanche conditions.

  • On Monday and Tuesday, snow levels are expected to be as low as 500 feet.
  • On Wednesday, snow levels are expected to reach as high as 3,000 feet.
  • For the rest of the week, snow levels are expected to be around 2,000 feet.

What’s next

The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.

The takeaway

This case highlights growing concerns in the community about repeat offenders released on bail, raising questions about bail reform, public safety on SF streets, and if any special laws to govern autonomous vehicles in residential and commercial areas.
