Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

Back-to-back flooding disasters in recent years — in Texas, New Mexico and Kentucky, among many others — have showed that preparing for flash flooding is a new necessity as the planet warms. And there’s no more dangerous time for a flash flood than after dark;
