Heat Safety Tips

A heat wave will bring hot temperatures to parts of SW Oregon and northern California Sunday through Tuesday. High temperatures of 90-100F with some west side valleys 100-105F and 105-110F in western Siskiyou County will bring levels of HeatRisk to moderate to major levels. Those sensitive to heat or without adequate cooling and/or hydration could experience heat-related illnesses.

A moderate risk for heat related illnesses continues through Tuesday for west side valleys, low-lying areas in Siskiyou and Modoc counties, and the Klamath Basin. This means this level of heat affects anyone without effective cooling and/or adequate hydration. Stay aware of local conditions as well as your own condition, and remember that area waterways are still cold!

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.

With the first Advisory-level temperatures expected for the area over the weekend, please consider these tips for ensuring the safety of yourself and those around you during this period of elevated temperatures.
