It's been a wild week of weather in many parts of the United States. Millions of people are enduring dangerous heat and humidity in the Midwest, while an Alaska landslide killed one man and a woman died in a Grand Canyon National Park flash flood. Additionally, Hawaii was pounded with rain from Tropical Storm Hone and mountains in the West saw early-season snow.

Flooding in the Midwestern U.S. has collapsed a railroad bridge and is testing a dam after days of heavy rains that have forced hundreds of people to evacuate or be rescued. The flooding brought additional misery to parts of Iowa, Nebraska, South Dakota and Minnesota as temperatures approached 100 degrees Monday. More rain is forecast, and many streams may not crest until later this week as the floodwaters slowly drain. Governors of the affected states say the flooding has damaged roads and bridges, shuttered or destroyed businesses, required hospitals and nursing homes to evacuate, and left cities without power or drinking water.
