What is indicated by a weather "warning"?

A weather "warning" indicates that hazardous weather is actually occurring. This terminology is used by meteorologists and weather services to convey that severe weather events are currently happening and pose a significant risk to life and property. For instance, when a tornado warning is issued, it means that a tornado has been sighted or indicated by radar, and immediate actions should be taken for safety.

In contrast, other options imply different levels of concern. For example, the notion that weather is about to clear up relates to improving conditions rather than a warning of danger. Likewise, a statement that hazardous weather is possible refers to a potential risk, which would typically be classified as a "watch" rather than a "warning.” The idea that conditions are expected to worsen suggests an anticipation of future adverse weather and would also not qualify as a current hazard as identified in a warning. Therefore, the accurate interpretation of a weather warning is that it signals immediate danger and a need for action.
