A flood advisory is a notification issued by weather authorities to inform the public about potential flooding in a specific area. It indicates that conditions are favorable for flooding, but it may not be severe enough to warrant a flood warning. People are advised to stay alert and take precautions, especially in low-lying areas or near rivers and streams. These advisories are part of a broader system of weather alerts, which also includes flood watches and warnings. The goal is to keep communities informed and safe by providing timely information about changing weather conditions and potential hazards related to flooding.
