A storm system will bring heavy rain and snow to King County this weekend.
The National Weather Service in Seattle expects one to three inches of rain in the western half of the county. This could lead to flooding on some rivers in the region, with the potential for some urban and street flooding by late on Saturday. A Flood Watch is posted through Sunday afternoon, October 22. Be alert to changing conditions, and never drive through flooded roads. To help prevent street flooding, clear leaves and other debris away from storm drains.
