There will be a moderate risk for heat related illnesses Monday and Tuesday. The Umpqua valley has been removed from the area of concern, leaving the Rogue, Illinois, Applegate, Klamath, Scott, and Shasta valleys, as well as the Mount Shasta area within the Heat Advisory. This level of heat affects anyone without effective cooling and/or adequate hydration. Temperatures will trend cooler for the latter half of the week.
Drier conditions return Sunday and temperatures will begin to warm. Temperatures warm to 15-20 degrees above normal on Monday and Tuesday, then may cool steadily into the end of next week. Temperatures will remain warm until the next low arrives Friday. Rain chances return with the next low as well.
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.
