Our Alert Nassau Citizen Alerts system is part of the Alert Florida Statewide Notification System, a mass notification tool that lets public safety officials rapidly warn the population about imminent or sudden hazards via phone, text message, email, social media, and mobile apps.

Residents, business owners, and visitors who want to receive these local alerts must “Opt-In” via the secure Alert Nassau Citizen Alerts website and provide their personal contact and location information. Choose a username and password you will remember – you will need them to log back into Citizen Alerts to make changes.
