River wind and hill snow across Portland
The river gives Portland fog and damp along Riverside and the center, and wind up the valley from the Sound in storms, so river-facing slopes lose tabs. The hills behind take heavier snow and ice at the eaves on warm-attic raised ranches. Mature trees shade the center streets and fill gutters every fall, while the newer subdivisions are more open. Freeze and thaw through the winter works at the old chimneys, and summer storms bring gusts across the river flats.
