How we respond to severe weather and flooding
Before severe weather hits, King County staff shift into emergency response mode. Field crew work shifts are changed from their normal daytime hours to two 12-hours shifts that allow for around the clock storm and safety response in unincorporated King County.
The 24/7 Road Helpline is staffed with more customer service agents to perform call intake and rapid deployment of the storm safety related incidents being reported. Communications teams monitor and report significant incidents such as road closures via the King County My Commute map. Road Alerts and X (Twitter) are used to relay information about unincorporated roadways affected by severe weather.
This page includes detailed information about how we respond.
Rainy season is here. You can help prevent local flooding by clearing leaves from storm drains on your property or next to your road. If your drain has a below-the-surface clog, you can report it to our 24/7 Road Help Line at 206-477-8100. We also offer free sandbags to help safeguard your home from flood.

When sloped areas become completely saturated by heavy rainfall, the risk of slides increases. While the likelihood of slides begins to decline after a day or more of dry weather, some deep-seated slides may occur days or even weeks to months after long periods of intense rainfall. Residents near mountain slopes, canyons, and slide prone areas should stay alert even after heavy rain subsides.
The King County Office of Emergency Management provides additional slide information including hazard-specific preparedness steps and response steps.
