Severe weather alerts

Severe weather alerts warn you when dangerous weather conditions are developing or already in progress in your area. These include thunderstorm warnings, tornado watches and warnings, flash flood advisories, winter storm and blizzard warnings, hurricane and tropical storm advisories, and extreme heat warnings.

Our alerts come directly from official meteorological agencies including the National Weather Service. A watch means conditions are favorable for severe weather — review your plan and stay alert. A warning means severe weather is imminent or already occurring — take protective action immediately.

Combine the alerts page with our weather radar maps to see exactly where storms are forming and moving, and with the hourly forecast to anticipate when conditions in your area are most likely to deteriorate.

Alerts are available for every U.S. city, state, and ZIP code. Bookmark this page during severe weather season for quick access to live warnings in your area.
