Story

The King County Flood Warning Center closed at 9:30 p.m. on Tuesday, March 1, as river flows stabilized following widespread minor and moderate flooding from a powerful rainstorm that dumped several inches of rain across the region.

The Flood Warning Center opened at 8:30 a.m. on Monday, Feb. 28, to monitor minor flooding along the Snoqualmie and Tolt rivers. Minor flooding then struck Issaquah Creek along with the Cedar, Green and White rivers. The Snoqualmie, Tolt and Green rivers all reached moderate flood phases, with floodwaters fanning out across low-lying areas and leading to numerous road closures. 

Flood patrol crews went to river corridors across King County to monitor conditions and reported their findings back to the Flood Warning Center. During river flooding events, King County serves as a clearinghouse for information on flood conditions, operating a recorded message center with continuous updates of river gauge readings and flood phases and other related information.
