The Public Alert System is a communication network designed to inform the public about emergencies and safety threats. It uses various channels, such as radio, television, and mobile devices, to deliver timely alerts about severe weather, natural disasters, or other urgent situations. This system helps ensure that people receive critical information quickly to take necessary precautions. Alerts are typically issued by government agencies, such as the National Oceanic and Atmospheric Administration (NOAA) or local emergency management offices. The system aims to enhance public safety by providing clear instructions and updates, allowing communities to respond effectively to potential dangers.
