Aerial footage from Thursday December 11th, shows deputies from the King County Sheriff's Office Marine Rescue Dive Unit assisting residents from Duvall, Washington as many in the area experience flooding this week.

Record floodwaters began slowly receding in Washington state on Friday after triggering evacuations, inundating communities and prompting dramatic rescues from rooftops and vehicles. But authorities warned that waters would still be high for days, and that danger from potential levee failures remained.

An unusually strong atmospheric river dumped a foot (30 cm) or more of rain in parts of western Washington over several days and swelled rivers. Gov. Bob Ferguson said no deaths have been reported

Authorities have yet to estimate the costs, but photos and videos show widespread damage, with entire communities or neighborhoods flooded around western and central Washington. Officials have conducted dozens of water rescues, debris and mudslides have closed highways, and raging torrents have washed out roads or bridges.

Officials issued “go now” orders Wednesday to tens of thousands of residents in the Skagit River flood plain north of Seattle, including the farming city of Burlington, home to nearly 10,000 people.

More rain is expected beginning Sunday.
