Millions swelter as temperatures soar across the US, while floodwaters inundate the Midwest

By The Associated Press

Millions of Americans sweated through yet another scorching day, while floodwaters forced evacuations in parts of the Midwest, including a town in Iowa whose own water-level gauge was submerged. One person was killed during flooding in South Dakota, the governor said. From the mid-Atlantic to Maine, across the Great Lakes region, and throughout the West to California, public officials cautioned residents about the dangers of excessive heat and humidity. In Oklahoma, the heat index — what the temperature feels like to the human body — was expected to reach 107 degrees on Sunday. The National Weather Service warned of the potential for rare tornadoes in the Northeast later Sunday.
