Weather Alert Meaning Decoder
Choose an alert type to see what it means, how urgent it is, and what actions to consider.
This tool explains common alert terms. Always follow official alerts and instructions from the National Weather Service, local emergency management, law enforcement, and other authorities.
Live conditions are tracked on the HazardNow dashboard
For current alerts, infrastructure stress, weather, wildfire, travel, public-health, supply-chain, and stability indicators, open the live dashboard.
Watch vs Warning vs Advisory
- Watch: Be prepared; conditions favorable or possible.
- Warning: Take action; hazard occurring, imminent, or likely.
- Advisory: Use caution; less severe than warning but still disruptive.
