What we covered
• Dangerous storms plow east: Intense and violent tornadoes have destroyed homes and farms in Missouri and Arkansas, as well as toppling a radio tower in Indiana. About 14 million people are under tornado watches from Ohio to Mississippi.
• Once-in-a-lifetime flooding: Wednesday’s storms will start multiple days of nearly nonstop rain that could trigger “generational” flooding in Arkansas, Missouri, Tennessee and Mississippi, forecasters warned.
• Supercharged rainfall: Climate change is making extreme rainfall more likely. It has intensified hourly rainfall rates in nearly 90% of large US cities since 1970, a recent study found.
