The first warm up for summer is expected this weekend with triple digits expected for West Side Valleys and 90s for the East Side. There will be a moderate risk for heat related illnesses Sunday and Tuesday, with a major risk of heat related illnesses expected on Monday for valleys west of the Cascades. This means this level of heat affects anyone without effective cooling and/or adequate hydration. Considering this will be the warmest temperatures of the year so far, many folks aren’t used to this kind of heat yet. Take it easy out there this weekend, and remember that area waterways are still cold! Temperatures will trend cooler for the latter half of the next week.
With warmer temperatures on the way, it’s good to remember that area waterways remain cold and rivers are swift. Wear a life jacket, limit time in cold water, never swim alone and have a flotation device that can be thrown to someone in need.
