High Pressure Dome Brings Dangerous Heat to Washington

A large dome of high pressure is settling over eastern Washington and creating what meteorologists call a "Major Heat Risk", Level 3 out of 4.

An Extreme Heat Watch is in effect for the Columbia Basin, Central Oregon, the Blue Mountain foothills, Simcoe Highlands, and the Yakima and Kittitas Valleys through Tuesday evening.

The worst of the heat is expected to peak today and tomorrow (Monday and Tuesday).

Even if you’re used to summer heat, this kind of prolonged and intense spike can be hard on the body, especially if you are not prepared. The NWS and Washington State health experts have a few reminders to help keep you safe.

It’s tempting to treat this like any other hot day, but don't. When temperatures soar this fast, your body does not have time to adapt. Make sure you know the signs of heat-related illness (like nausea, dizziness, rapid pulse, or confusion), and do not hesitate to seek help if needed.

Stay safe and cool out there!
