Keeping life on the West coast interesting, Typhoon Chaba will be dressing up as a midlatitude cyclone for Halloween and will then "amplify into an extraordinarily deep low pressure center," says the UW's Cliff Mass. The result, for our purposes, is that we're going for a ride on the pineapple express. Says Mass:

I am sure the National Weather Service will be putting out some statements on potential flooding of rivers coming off the Olympics and N. Cascades. At this point it does not look like a situation that would produce urban flooding over the Puget Sound population areas.

We'll better know in a day or two how much rain Seattle will get, so keep an eye on UW's Probcast. And while you're doing that, it's a good time to announce that you can pick up your storm-drain "Fall Clean" supplies for free at Seattle Public Untility's warehouse (3633 East Marginal Way South) this Saturday, October 30, 9 a.m. to noon. That includes such goodies as: rakes, bags, gloves, shovels, brooms, and dustpans!
