“Back-to-back” storms driving “once in a generation flooding” threaten millions of Americans with a “catastrophic risk to life” weather event.
A “rare and dangerous” union of deadly atmospheric conditions spanning thousands of miles will this week hit almost 20 US states.
Severe thunderstorms, tornadoes and near-100mph winds will unleash the most destructive rainfall in records going back 1,000 years.
Eastern regions are most at risk, experts warn, although central and southern regions are under a raft of rain and flood warnings.

AccuWeather meteorologist Jonathan Porter said: “We are forecasting a catastrophic risk to lives and property from flash flooding for the first time since Helene brought historic flooding to western North Carolina last September.
“Relentless rounds of rainfall and back-to-back storms could quickly trigger catastrophic flooding and people need to be prepared for a life-threatening flooding emergency.
“This is a rare and dangerous atmospheric setup.”
The US National Weather Service (NOAA) has issued flood and storm warnings across Texas, Louisiana, Arkansas, Indiana, Alabama, Kentucky, Georgia and surrounding states.
Further east, flash flood warnings are in force as a ‘Caribbean atmospheric river’ offloads across the Atlantic coast.
Atmospheric rivers, a more typical Pacific-coast feature, carry huge amounts of moisture triggering intense, heavy and rapid rainfall.
