A dangerous stretch of extreme heat is set to hit Pendleton, Ore., and surrounding regions of north-central Oregon and southeast Washington starting Tuesday morning. The National Weather Service has issued an extreme heat watch, warning that triple-digit temperatures will persist through Thursday evening, creating hazardous conditions for many residents.
Highs in the Columbia Basin, Yakima Valley, and Tri-Cities region could soar as high as 102 degrees, with several cities at risk of breaking daily temperature records. This prolonged heat will pose significant health risks, especially for vulnerable populations such as children, seniors, outdoor workers, and anyone without access to reliable cooling.
Cities affected by this extreme heat include Hermiston, The Dalles, Pendleton, Yakima, Walla Walla, and the Tri-Cities. Local authorities are advising residents to limit outdoor activities during the hottest parts of the day and to stay hydrated. Symptoms of heat illness—such as dizziness, nausea, and rapid heartbeat—should be treated as an emergency and require immediate medical attention.
The intense heat, combined with dry conditions, will also increase the risk of wildfires, especially in the foothill areas of the Blue Mountains. Local emergency managers are urging residents to take extra precautions, including checking on vulnerable neighbors, drinking plenty of water, and seeking shelter in air-conditioned spaces during peak heat hours.
The extreme heat watch will be in effect from Tuesday morning through Thursday evening, with updates provided if the situation worsens. Residents are urged to stay informed and prepare for the intense heat that lies ahead.
