As you may have already experienced we've seen quite a bit of rain since Thursday and are expecting quite a bit more this weekend. Forecasters are calling for heavy rain through Sunday. The North Cascades highway is temporarily closed for the weekend, due to avalanche risk, and our crews are watching Chinook and Cayuse passes closely.

Crews have been out clearing storm drains, but you should still keep an eye out for urban or small stream flooding. Forecasters are expecting most mainstream rivers to flood due to the significant amount of rain. Here's where you can keep up with those river levels: Remember, do not drive through standing water, it only takes six inches of water to stall a vehicle and a foot of water to float most vehicles.  Better safe than sorry.

This atmospheric event is also hitting the Olympic Peninsula rather hard.  We've already seen trees down along SR 112, and road closures up near La Push due to water over the roadway from the Bogachiel River.

The Pysht River is on the rise in Clallam County, as seen here on SR 112 near milepost 28.

The mountains aren't immune to this event. Here's the extended forecast:

  • Saturday night:  Rain. Potential turn to wet snow pass area by Sunday morning.
  • Sunday: Morning snow concern pass and west side.  Snow concern later in the day and evening potentially under 2,000 ft.
  • Sunday night: Snow concern through late evening west of Snoqualmie Pass area down to under 2,000 ft., then easing up late night with solid freeze.

If you need to go anywhere, go prepared.

Stay informed
We'll be continuing to update the travel alerts section of our website throughout the weekend and will be posting on Facebook and Twitter if there are significant closures.
