Monroe County's Alert!Monroe uses the Everbridge emergency notification system to alert residents about various emergencies, including severe weather, fires, and flooding. Alert!Monroe can also send routine announcements, such as road closures and water utility maintenance.
Messages will be sent to residents on their preferred contact paths — cell phone, SMS (text), home phone, email, fax, or pager — to ensure real-time access to potentially lifesaving information. Residents listed in the Monroe County public white/yellow page database will be automatically subscribed to alerts by phone, but Everbridge allows citizens to self-register, provide additional contact information, or opt-out.
