PLEASE NOTE: You may have previously signed up for Swift911. Your information was migrated to this new system so you would not miss alerts and notifications during the transition period. However if you did not create a SIREN account/profile by December 31, 2022 you are no longer in the system. Please sign up at the link above, select your notification preferences, and how you wish to receive alerts (voice, text, email).  

This service is provided by your local government at no cost to the public; however, message and data rates may apply depending on your provider and phone services. Please refer to your mobile phone's service plan for more information.
