The Flood Warning Center opened at 8:30 a.m. Thursday to monitor minor flooding along the Tolt River. A few hours later, the Snoqualmie River also reached a Phase 2 flood alert, with minor flooding in low-lying areas along the river. The Tolt River eventually reached a Phase 3, with moderate flooding noted upstream of Carnation.

Flood patrol crews logged several hours in the field throughout Thursday to monitor conditions and report 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.
