Don’t be concerned about us: we live on a basalt ridge that survived the Missoula Floods 13,000 years ago. But when a warming trend and rain simultaneously hits the west coast (Seattle) and holds all the way across, we not only have abundant rain, but a lot of winter snow starts melting all at once, and the snow level on this system is set to rise fast. The usual areas of Spokane are likely to take on water, an area called something like Happy Valley, Riverside Drive, and the area along the St Jo—as the Spokane and Little Spokane and St Jo rivers all head westward, joined by snowmelt from the mountains. The waterfalls, like Palouse Falls and Multnomah, will get pretty.
On the other hand, in Seattle, motorists will be assisting confused salmon to cross the roads, that sort of thing (there are photos) and low lying areas will, again, flood. Snoqualmie Falls should be something else, as major snowmelt comes down from the Cascades.
This is when the Pacific NW tends to believe spring is coming, and will be a good time to start thinking about the fishes. This morning, a last gasp of winter, we had hoarfrost on things, which has now gone. But I think we are, after a chaotic winter, going to make the ‘melted by St Paddy’s Day’ normalcy for the shift toward spring.
