Summary
- Millions under heat-related alerts from the National Weather Service
- Extreme heat can trigger life-threatening illnesses, especially for vulnerable groups

As of August 25, 2025, the Pacific Northwest is gripped by a severe heatwave, with the National Weather Service (NWS) issuing extreme heat warnings and advisories across multiple states. Millions of people are under heat-related alerts, as the agency warns of "dangerously hot conditions" that could pose serious health risks.
According to the Centers for Disease Control and Prevention (CDC), extreme heat can trigger life-threatening illnesses, particularly among vulnerable populations such as older adults, young children, and those with certain medical conditions. The agency notes that extreme heat contributes to over 700 deaths annually across the United States.
In California, cities like Bakersfield, Fresno, McKittrick, and Coalinga are expected to see high temperatures reaching up to 104 degrees Fahrenheit. Meanwhile, in Washington, Seattle, Eastside, and the Lowlands of Pierce and Southern King Counties are facing hot conditions with temperatures in the upper 80s to low 90s. Portland, Oregon and surrounding areas could see highs of 90-98 degrees, while Lewiston, Idaho is forecast to experience triple-digit temperatures.
The NWS has advised residents to stay hydrated, seek air-conditioned spaces, and check on vulnerable neighbors and family members. They have also warned against leaving young children and pets unattended in vehicles, as the interior can quickly reach lethal temperatures.
Meteorologists predict the intense heat will continue through Tuesday, with some record highs potentially being challenged. The heatwave is expected to start easing by Wednesday, but temperatures will remain above average for the rest of the week.
