They say Seattle rain is frequent but not forceful, more like a reliable drizzle than an occasional cataclysm. Usually that’s about right. As a bicyclist, this means that the weather forecast isn’t much use. If you only ride when the forecast isn’t 100% rain, you’ll only ride for two months a year. Most of the time, those rainy days are fine for outdoor activity. Tonight we played frisbee in the park, and the drizzle was not an obstacle.
Unfortunately, there are exceptions. Last night was a big one, a record-breaking storm and one of the worst weather rides of my life. Rolling home about 7 miles from rehearsal, the Seattle skies opened up like an old-fashioned New England downpour. I rode with near zero visibility, through flowing water over poorly lit cracked concrete roads, often with no bike lane. I wrung water out of my socks when I got home, mostly just to prove that they were as soaked as they felt.
It occurs to me that the real problem here is the silly percentage precipitation indicator. In Seattle, at least, what matters on any given day is the total expected rainfall, in millimeters … or even better, the peak instantaneous predicted precipitation rate. I bet I could get that info somewhere…
EDIT: Looks like that storm actually broke the record.
