Overview

• Portland saw steady rainfall into early afternoon with frequent gusts of 25–35 mph, and a Wind Advisory was posted north of Central Oregon in the Lower Columbia Basin and Wasco County.
• Saturday turns showery and mild with breaks possible, another front arrives Sunday, and weekend rainfall is projected at 0.50–1.0 inch in valleys with up to 3 inches in the Coast Range and Cascades.
