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.

NOAA's GOES West (GOES-18) satellite has been closely tracking a potent and persistent atmospheric river that has brought torrential rain and high winds to the Pacific Northwest this week. The threat for major river flooding and landslides continues across portions of western Washington and northwest Oregon today. Latest: www.weather.gov | NOAA Satellite and Information Service
