Even in places where the floods have let up, the storm isn’t over: Floods can lead to excess deaths long after the actual event. “The health impacts of flooding aren’t just immediate,” wrote Katelyn Jetelina last week in her newsletter, Your Local Epidemiologist. “They often unfold over weeks and months.”

The forecast comes on the heels of heavy rain in Louisiana and Mississippi on Thursday, major and disruptive flooding that forced a state of emergency in New Jersey, and deadly flash floods in Texas that took the lives of at least 135 people, including children at a Christian girls’ camp.
