Warning systems are designed to alert people about potential dangers or emergencies. These systems can include alarms, sirens, and notifications sent through various media, such as text messages or social media. They are often used in situations like severe weather, natural disasters, or public safety threats to ensure that individuals can take appropriate action. Many warning systems are integrated with technology, such as satellites and radar, to monitor conditions and provide timely alerts. For example, National Weather Service uses these systems to warn communities about storms or floods. Effective warning systems can save lives by giving people the information they need to stay safe.
