Warning systems are designed to alert people about potential dangers or emergencies. These systems can include alarms, sirens, or notifications sent through various media, such as mobile phones or social media. They are commonly used in situations like severe weather, natural disasters, or public safety threats to ensure that individuals can take appropriate action. Many warning systems rely on technology to monitor conditions and disseminate information quickly. For example, the National Weather Service uses radar and satellite data to issue alerts about storms or floods. Similarly, emergency management agencies implement warning systems to inform communities about hazards, helping to save lives and reduce damage.
