Superfloods

 

I have questions.

The deadly flash floods in Texas over the 2025 Fourth of July weekend were just the latest reminder of an alarming new reality: Once-rare "superfloods" are striking with unprecedented ferocity, devastating communities around the globe. Join investigators as they piece together a moment-by-moment account of the Asheville, North Carolina disaster in 2024, when Hurricane Helene triggered flash floods and mudslides in a city 2,000 feet above sea level and more than 250 miles inland. Discover how hidden atmospheric phenomena, combined with a warming planet, are creating a new era of risk. Can science offer a lifeline to communities facing an increasingly dangerous future?

Science sommelier: The episode pairs nicely with NOVA's Weathering the Future.
