Record high temperature are forecast for Sunday as a dangerous heat wave threatens large swaths of the country.
Temperature are expected to hit triple digits in Arizona.
“Take the heat seriously and avoid time outdoors,” the National Weather Service said 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.”
Heat warnings and advisories are in place from the Pacific Northwest to California, to parts of the Southern Plains, central Gulf Coast and the southern most part of Florida.
Meanwhile, Italian authorities have issued an “extreme” health risk this weekend for 16 cities including Rome and Florence, amid a heat wave baking Europe.
