Warnings, watches and advisories: what they mean
The National Weather Service uses three main levels. A warning means a hazard is happening or about to happen and threatens life or property, so act now. A watch means conditions are favorable for a hazard to develop, so get ready. An advisory covers weather that is less serious but still disruptive, such as slick roads or high heat. Read the full guide to watches and warnings.
This map shows every active alert for land areas in the 50 states, Washington, D.C. and Puerto Rico. Counties are shaded by the most serious alert affecting them, and storm-based warnings such as tornado and severe thunderstorm warnings are drawn as the exact polygon the forecasters issued.

Frequently asked questions
How often are the alerts updated?
The alert lists on each page refresh from the National Weather Service every hour. The live map loads current alerts directly from the NWS each time you open it.
Where does this data come from?
Active alerts come from the National Weather Service public alerts API. Alert history comes from the Iowa Environmental Mesonet archive of NWS warnings, and tornado history from the NOAA Storm Prediction Center database.
How do I see alerts for my location?
Use the "Alerts for my location" button, or choose your state and county. County pages list every alert that includes that county.
Is this an official National Weather Service website?
No. It is an independent site that republishes public NWS alerts in an easier format. Always follow official warnings and local emergency officials.
