Snohomish County Alerts

Snohomish County is a wonderful place to live, but there are risks that come with our mountains, trees and rivers. Mountains can have severe weather, hills can slide, trees can catch fire and rivers can flood.

One way to stay safe is to receive notice of potential danger as early as possible. You can make that happen for yourself, your family, your friends and your neighbors. There are several options, all easy and free.


Powered by Smart911, SnoCoAlerts is the county’s early warning system and notification system. You can choose what activities you want to be alerted about. Your zip code and address are used to tailor alerts for where you live. You can add more alerts or update your contact methods at any time.


Sign up for GovDelivery to receive information and tips on disaster preparedness including upcoming community events and workshops available in Snohomish County. You can choose whether you would like to receive information by email or text messages.


If you use a cell phone (and even if you don’t), you will want to sign up for Smart911. You can store critical information for use by emergency responder’s. Please list your emergency contacts, home address and any medical conditions to assist the first responder’s.

These services are national organizations, not run by the County, but they do coordinate closely with Snohomish County 911 dispatch and with the county’s emergency management team.
