Millions of Americans sweated through a scorching weekend as temperatures soared across the US, while residents were rescued from floodwaters that forced evacuations across the Midwest. One person died 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. Forecasters say the heat wave will continue early in the week in the Southeast, portions of the South and the Plains.
