Getting Started with Weather Alert Types in the United States

Understanding weather alerts is crucial for safety during hazardous conditions. In the United States, the National Weather Service (NWS) issues various alerts to inform the public about potential weather hazards.

What Are Weather Alerts?

Weather alerts are notifications issued by the NWS to inform the public about impending or occurring hazardous weather events. These alerts are categorized based on the severity and immediacy of the threat.

What Are the Main Types of Weather Alerts?

The primary types of weather alerts include:

• Advisory: Highlights special weather conditions that are less serious than a warning. They are for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.

• Alert: Automated Local Event Reporting in Real Time (ALERT). Network of automatic raingauges that transmit via VHF radio link when precipitation occurs. Some sites are also equipped with other sensors such as temperature, wind, pressure, river stage or tide level.

• Outlook: An outlook is used to indicate that a hazardous weather or hydrologic event may develop. It is intended to provide information to those who need considerable lead time to prepare for the event.

• Warning: Issued when a hazardous weather or hydrologic event is occurring, is imminent, or has a very high probability of occurring. A warning is used for conditions posing a threat to life or property.

• Watch: Used when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, and/or timing is still uncertain.

How Do These Alerts Differ?

The key differences among these alerts are based on the severity and immediacy of the threat:

• Advisories are issued for less severe conditions that may cause inconvenience but are not immediately life-threatening.

• Alerts are real-time notifications about specific weather events, such as precipitation, that are occurring or imminent.

• Outlooks provide early indications of potential hazardous weather, allowing time for preparation.

• Warnings are issued when hazardous conditions are occurring or imminent, posing a threat to life or property.

• Watches indicate that conditions are favorable for a hazardous event but are not yet occurring.

How Should You Respond to These Alerts?

• Advisories: Stay informed and exercise caution.

• Alerts: Take immediate action as directed in the alert.

• Outlooks: Monitor updates and prepare as necessary.

• Warnings: Follow the recommended safety measures promptly.

• Watches: Stay alert and be prepared to act if conditions worsen.
