Forecasters said rain-gorged Issaquah Creek has appeared to have crested by late Sunday afternoon.
The creek’s lower reach near Lake Sammamish State Park remained near flood stage, but National Weather Service forecasters in Seattle said although Issaquah Creek had crested, a flood warning is to remain in place until late Sunday night.
Residents can receive real-time Issaquah Creek flood data from flood gauges in Hobart and near the mouth of Issaquah Creek.
Though emergency planners monitor both gauges, only the Hobart gauge is used to determine flood phases in Issaquah.
Forecasters said the gauge near the creek mouth recorded the water level at 10.6 feet at 4:30 p.m. Sunday. The flood stage for the area is 10.5 feet. The creek level should recede from flood stage by 8 p.m. Sunday.
City crews fanned out across Issaquah on Sunday as a late-fall deluge led to flooding in neighborhoods and caused the creek to rise.
Residents reported street flooding from Montreux on Cougar Mountain to the business district along Northwest Gilman Boulevard to downtown Issaquah. Drivers also reported water flowing across Issaquah-Hobart Road Southeast in rural King County.
The heavy rainfall and unseasonably warm temperatures should continue to impact Western Washington through Monday, although rainfall is expected to taper off Sunday night. Forecasters said the Pineapple Express is the wettest system to affect the region in almost two years.
