Levees breach, forcing thousands to evacuate Central U.S. floods

• Meanwhile, 2,400 Oklahomans have been evacuated after massive thunderstorms dumped epic rains in Oklahoma and surrounding states.

What to watch: Floodwaters are slowly making their way down the Mississippi River toward Louisiana, where the river is expected to crest at the Morganza Spillway by June 2, at the second-highest level on record. Heavy rain will return to the Southern Plains in the first week of June.

The big picture, via Axios' Andrew Freedman: The ongoing flooding is consistent with scientific studies showing the increasingly apparent effects of human-caused climate change. A warmer atmosphere holds more water vapor on average, which contributes to an uptick in heavy precipitation events. These trends have been seen in much of the U.S. in recent decades.
