Remember the devastating Tennessee flash flood from 8/21? 9.34" of rain fell in 3 hours, with multiple fatalities and catastrophic damage.

Radar estimates already show a much larger - and much more populated - swath of >7-8" in 3 hours in NJ.

This is how serious today is. https://t.co/ygcPWdi6Zf pic.twitter.com/niDQeucDxe
