Temperature records are forecast to be broken Sunday as a dangerous heat wave threatens large swaths of the country with potentially deadly triple digit highs.
“Take the heat seriously and avoid time outdoors,” the National Weather Service warned in a bulletin early Sunday. “Temperatures will reach levels that pose a health risk and are potentially deadly to anyone without effective cooling and/or adequate hydration. Heat is the leading weather-related killer in the U.S.”
Excessive heat warnings and advisories are in place “from the Pacific Northwest, California, and the Great Basin to parts of the Southern Plains, Central Gulf Coast, and southern tip of Florida,” the bulletin said.
