Urban flooding is new danger after storm
January 21, 2012 · Updated 2:01 PM
Storms of ice and snow may have passed, but changing temperatures bring a new danger: Flooding.
Rain and melting snow will mean higher rivers and inundated streets and lawns.
The Valley's main roads were mostly bare and drivable by Saturday, Jan. 21. But the remaining banks of snow are clogging storm drains, and local urban flooding is already happening due to rain and melt.
City officials in Snoqualmie and North Bend ask that residents locate and clear storm drains near their homes, helping with the flow by breaking down the ice and clearing debris. Public Works crews are working on this issue, but need proactive resident and business owner assistance to reach all affected drains.
"The thick, wet snow acts as a dam and water cannot make it to many of the drains," said North Bend's Wilson. "This will cause flooding into the streets."
High rivers ahead?
Flood tracking agencies are already predicting high rivers in the week ahead. Lower Valley flood gage collator Floodzilla predicts the Snoqualmie cresting just below flood stage at 4 a.m. Thursday, Jan. 26. River flows are now rising.
