Severe weather poses significant risks across the United States, making it crucial for residents to understand weather alerts and take appropriate actions. This guide provides an overview of severe weather alerts, their meanings, and how to stay safe during extreme weather events.

What Are Severe Weather Alerts?

Severe weather alerts are notifications issued by the National Weather Service (NWS) to inform the public about hazardous weather conditions. These alerts are categorized into watches, warnings, and advisories, each indicating the severity and immediacy of the threat.

What Is the Difference Between a Watch and a Warning?

Understanding the distinction between a watch and a warning is vital for timely and appropriate responses:

Watch: Indicates that severe weather is possible in or near the watch area. It serves as a heads-up to stay alert and prepared. For example, a Severe Thunderstorm Watch means that conditions are favorable for severe thunderstorms to develop. (weather.gov)
Warning: Means that severe weather is occurring or imminent. Immediate action is necessary to protect life and property. For instance, a Severe Thunderstorm Warning indicates that a severe thunderstorm has been reported by spotters or indicated by radar. (weather.gov)
