My biggest problems were trying to figure out if I could drive my car through the water in some of the low-lying intersections in the Montlake neighborhood. (You don't think about how little clearance a Miata has until you're faced with a few inches of standing water.)

My house is on a hill, so I wasn't worried about flooding at home. Mud/land slides, on the other hand...I wasn't really sleeping very restfully for a couple of days. Last winter (sometime early this year), there was a slide on one of the properties a couple of doors down from me. I'm constantly waiting for the ground to slip out from underneath the house I live in. (With any luck, I'll be moving in a couple of months and won't have to think about that anymore.)
