Spokane, Wash. – A prolonged stretch of dangerous summer heat is set to intensify across the Inland Northwest this week, with temperatures climbing into the upper 90s and some communities expected to reach the triple digits by Tuesday and Wednesday.
According to the National Weather Service in Spokane, a Moderate to Major HeatRisk will develop across much of eastern Washington and northern Idaho as temperatures steadily increase through the week. The greatest concern is expected from Tuesday through Thursday, when prolonged daytime heat and warm overnight temperatures could increase the risk of heat-related illnesses, particularly for people without effective cooling.
Communities including Spokane, Wenatchee, Lewiston, Coeur d’Alene, Ritzville, Omak, Grand Coulee, Moses Lake, Pullman, Colville and Bonners Ferry are expected to experience the hottest conditions. Several locations are forecast to remain under a Major HeatRisk for multiple consecutive days, meaning the heat could become dangerous for anyone lacking adequate hydration or access to air conditioning.
Residents should drink water before becoming thirsty, wear lightweight and light-colored clothing, and avoid strenuous outdoor activities between 10 a.m. and 4 p.m. Fans alone may not provide enough protection during the hottest part of the day, so those without air conditioning should seek out cooling centers or other air-conditioned spaces. Check on older adults, young children and neighbors who may be especially vulnerable.
The hottest weather is expected to peak by midweek before temperatures begin easing later in the week. Forecasters encourage residents to monitor the latest updates, as additional heat advisories or warnings may be issued if temperatures continue to climb.
