An "Advisory" is a formal recommendation or warning issued by an organization or authority to inform the public about potential risks or important information. It can cover various topics, such as weather conditions, health concerns, or travel safety. For example, a weather advisory may alert people to severe storms, while a health advisory might provide guidance on disease outbreaks. Advisories are typically issued by government agencies, such as the National Weather Service or the Centers for Disease Control and Prevention (CDC). They aim to help individuals make informed decisions and take necessary precautions to ensure their safety and well-being.
