Heat wave in forecast: 'Most common cause of weather-related deaths'

EUGENE, Ore. - So long, drenching rains. Hello, extreme heat.

Temperatures could push 90 F or higher in the Willamette Valley, with parts of southern Oregon and northern California facing temperatures in the triple digits.

And that old saw about a "dry heat" and cool nights won't apply at first.

"Humidity left over from our recent rains will make it feel muggier than usual," forecasters said, "and nights will be slow to cool off."

Beyond the discomfort of sticking to the bed sheets, high temperatures carry serious health risks.

"Extreme heat events, or heat waves, are the most common cause of weather-related deaths in the United States," the Centers for Disease Control and Prevention notes. "They cause more deaths each year than hurricanes, lightning, tornadoes, floods, and earthquakes combined."

Forecasters encourage the elderly and others susceptible to heat illness to watch weather forecasts as temperatures heat up this week and weekend.

"Those sensitive to heat should stay tuned for updates over the coming days as details about next week will become clearer," the National Weather Service said. "Now is a good time to consider how best to take a break from the heat in case a prolonged heat wave materializes over the coming days."
