The National Weather Service issued an excessive heat watch for western Oregon from Thursday afternoon through Friday evening.
Temperatures will range from the 90s to 100 degrees in the Willamette Valley, challenging record highs of 101 on Aug. 16 and 97 on Aug. 17.
Forecasters cautioned that physical activity like exercise or work in extreme heat can cause heat exhaustion or heat stroke.
"The Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments," the weather service said. "Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency: call 9-1-1."
In many ways, extreme heat is like a natural disaster. In fact, heat kills more Americans every year than earthquakes, lightning, floods, hurricanes and tornadoes combined, according to the Centers for Disease Control and Prevention.
Efforts to beat the heat can also prove dangerous.
Many of the fatalities during hot spells in the Pacific Northwest occur in and around
water," the weather service said. "Use extra caution around area waterways and be sure to wear a life jacket."
