The National Weather Service has issued a heat advisory for the Tri-Cities through Tuesday, although hot temperatures could last longer, according to the National Weather Service.
Saturday the high temperature is expected to be 103 degrees, climbing to 105 degrees Monday. Then highs are expected to remain in the 100s until Friday, when the high could drop to the high 90s.
People who work or spend time outside should take precautions, including scheduling strenuous activities for the early morning or evening, the weather service advises.
Nausea and cold, clammy skin can be a sign of heat exhaustion. If heat stroke is suspected because of a body temperature over 103 and a rapid pulse, 911 should be called immediately, according to the Centers for Disease Control.
