Portland, Ore. – Heat will intensify across northwest Oregon and southwest Washington over the next two days, with inland communities climbing into the mid to upper 90s and creating an increased risk of heat-related illness for people without reliable cooling. The hottest conditions are expected Tuesday and Wednesday, when cities across the Willamette Valley approach the upper 90s during the afternoon.
According to the National Weather Service in Portland, Moderate to Major HeatRisk is expected Tuesday and Wednesday as temperatures run well above normal. The agency warns that anyone spending extended time outdoors or without access to air conditioning could face a higher risk of heat-related illness, especially during the hottest part of the day.
Portland is expected to reach 96 degrees Tuesday and Wednesday, while Salem climbs to 97 degrees Tuesday before remaining in the mid-90s Wednesday. Eugene is forecast to reach 95 degrees Tuesday and 94 degrees Wednesday, while Corvallis tops out around 94 degrees Tuesday. Even areas along the lower Columbia, including Longview, Washington, are expected to reach the mid-90s.
The coast will remain considerably cooler, with Astoria in the 70s and Florence holding near the low 70s through midweek.
Residents should drink plenty of water, seek air-conditioned spaces if available, avoid strenuous outdoor activity during the afternoon, and check on older adults, young children, and others who are more vulnerable to extreme heat. Those working outside should take frequent breaks in the shade and stay hydrated.
Temperatures are expected to ease beginning Thursday, although many inland locations will still remain in the upper 80s to lower 90s. Additional heat statements or advisories could be issued if conditions become more hazardous.
