Portland, OR – A cold weather advisory is in effect across northern Oregon and southern Washington, with temperatures expected to plunge to 20-25°F. The advisory will remain active from 10 p.m. Tuesday through 10 a.m. Wednesday.
According to the National Weather Service (NWS) in Portland, affected areas include the Willamette Valley, the Coast Range lowlands, the Cascade Foothills, and parts of southern Washington, including the Cowlitz River Valley and North Clark County. Temperatures this low can cause hypothermia with prolonged exposure.
