PORTLAND, Ore. – Large portions of Oregon and southwest Washington will swelter under dangerous heat through Tuesday night, with highs reaching 97 to 105 degrees across much of the Willamette Valley, Columbia River Gorge, and central Oregon. Overnight lows staying in the upper 60s will offer little relief, keeping heat stress levels high.
According to the National Weather Service in Portland and Pendleton, the Extreme Heat Warning remains in effect until 10 p.m. Tuesday for Portland, Vancouver, Salem, Eugene, Bend, Hood River, and surrounding communities. Forecasters say the combination of extreme daytime heat and warm nights significantly increases the risk of heat-related illness.
Local officials urge residents to drink water frequently, limit outdoor activities to early morning or late evening, and check on elderly neighbors and those without air conditioning. Work crews and outdoor laborers should schedule frequent breaks in shaded areas. Car interiors can reach deadly temperatures within minutes — children and pets should never be left unattended.
Cooling centers remain open across the region, and residents can call 211 for shelter locations. Conditions are expected to ease slightly Tuesday night into Wednesday as cooler overnight temperatures return.
