In many ways, it is the anti-Sequim, anti-rainshadow.
A place of extraordinary precipitation near Puget Sound.
I am talking about the Spada Lake anomaly.
|Spada Lake is circled|
Verlot Ranger Station (elevation 980 ft): 135.5 inches
Big Four Ice Caves (elevation 1750 ft): 142.5 inches
Here are some gee-whiz numbers for Spada Lake precipitation:
Peak annual - 224 inches (1990-91)
Highest Month – 51 inches (November, 1990)
Wettest Day – 13 inches (November 11, 1990)
Folks, this is a REALLY wet place. In contrast, nearby Everett, gets only about 37 inches a year. The city of Everett has a reservoir there and let me assure you, they don't have a problem of lack of water. And will not have one under any imaginable circumstance. Official precipitation maps (see below) suggest the effect (although this map has its issue).
Although the winds were westerly and northwesterly at higher levels, southwesterly winds WERE observed during that period. To illustrate this, here are the winds from the Seattle profiler during 24-h of the events:
PS: For the lowland snow lovers in the crowd, there appears to be an enhanced chance of some light snow in some lowland locations on Sunday.....more on that tomorrow. No big storm though. And the long-term pattern is excellent for mountain snows... classic La Nina year late season snowfall! Don't put your skis away!
