This radar loop from 1 year ago this week shows how heavy rain before Helene, called a Predecessor Rainfall Event, followed by Hurricane Helene making landfall in Florida & dumping rain all across the southeast made for one of the worst natural disasters in U.S. history. If you watch when the heaviest rain hits western NC, it's raining heavy for about 3 days straight. Flash flood warnings and flash flood emergencies show up in red and purple boxes through the event.
