Understanding Weather Alert Thresholds During Severe Weather

Severe weather poses significant risks, making timely and accurate alerts crucial for public safety. In the United States, the National Weather Service (NWS) employs a structured system to communicate these risks, categorizing them into Watches, Warnings, and Advisories.

What Are Weather Alerts?

Weather alerts are notifications issued by the NWS to inform the public about impending hazardous weather conditions. These alerts are designed to prompt timely actions to protect life and property.

What Are the Different Types of Weather Alerts?

• Watch: Indicates that conditions are favorable for the development of severe weather. For example, a Severe Thunderstorm Watch is issued when thunderstorms capable of producing winds of at least 58 mph and/or hail 1 inch in diameter are possible. (weather.gov)

• Warning: Signifies that severe weather is imminent or occurring. A Severe Thunderstorm Warning is issued when a thunderstorm is producing winds of 58 mph or greater and/or hail 1 inch in diameter or larger. (weather.gov)

• Advisory: Alerts the public to less severe but still significant weather conditions that may cause inconvenience or minor damage. For instance, a Flood Advisory is issued when flooding is expected to cause minor flooding or inconvenience. (weather.gov)

How Are These Alerts Determined?

The NWS uses specific criteria to issue these alerts:

• Severe Thunderstorm Warning: Issued when a thunderstorm is producing or will produce hail 1 inch in diameter or larger and/or wind gusts of 58 mph or higher. (weather.gov)

• Tornado Warning: Issued when a tornado is occurring or imminent, based on radar indications or a reliable sighting. (weather.gov)

• Flash Flood Warning: Issued when flash flooding is imminent or occurring, typically within six hours of the event. (weather.gov)
