SMC Alert is San Mateo County’s primary alert and warning system used to contact you during urgent or emergency situations which may include life safety, fire, weather, accidents involving utilities or roadways or disaster notifications.
A few examples of the types of messages that can be sent through SMC Alert are:
Emergency situations:
🚨 Flood, Fire, Severe Weather, or Tsunami Warnings
🚨 Notify the community of the location of the nearest emergency shelter, available bed space, hours of operation during a crisis
🚨 Available evacuation routes during an emergency
🚨 Activate special teams within the community, such as CERT volunteers
🚨 Precautionary Warnings (optional subscriptions)
🚨 Crime Alerts
🚨 Major road closure such as a freeway
You can't be reached for the majority of non-life threatening emergencies if you don't register for SMC Alert — it’s an opt-in service so you must sign up in order to receive the alerts. Additionally, we will use other tools noted in this piece to try to reach you if you haven’t signed up.
You can set alerts to send emergency and non-emergency text and voice messages to your:
✉️ email accounts
📱 cell phones, smartphones, tablets
☎️ voice messages to landline phones (home & work)
SMC Alert is managed by the San Mateo County Department of Emergency Management (SMCEM). The service is available to all cities, towns and special districts within County of San Mateo - Government. Alerts may also be sent by local police, fire and emergency managers from other cities within San Mateo County.
