When severe weather threatens New York, the National Weather Service may issue either a watch or a warning. Knowing the difference can help you respond quickly and safely.
What is a weather watch?
A watch means conditions are favorable for severe weather to develop, but hazardous weather is not yet occurring or its exact timing and location remain uncertain.

Watches are typically issued for large areas and are meant to give people time to prepare and monitor changing conditions.
During a watch, you should:
- Monitor the latest forecasts and weather alerts.
- Review your emergency plan.
- Be prepared to move to a safe location if conditions worsen.
- Keep a way to receive weather warnings, such as a smartphone, local TV or radio, or NOAA Weather Radio.
What is a weather warning?
A warning means severe weather is occurring or is expected to occur soon in the warned area.
Warnings usually cover a much smaller area than watches and indicate there is an immediate threat to life or property. If a warning is issued for your location, take protective action right away.
What should I do during a tornado warning?
If a tornado warning is issued:
- Move immediately to a basement or an interior room on the lowest floor of a sturdy building.
- Stay away from windows and exterior walls.
- If possible, protect yourself with a mattress, blankets or a helmet.
- If you're in a mobile home, leave it and seek shelter in a sturdy building.
If you're outside or in a vehicle, go to the nearest substantial building if you can do so safely. Do not take shelter beneath a highway overpass.
What should I do during a severe thunderstorm warning?
Severe thunderstorms can produce damaging winds, large hail, frequent lightning and flash flooding.
If a severe thunderstorm warning is issued:
- Move indoors and stay away from windows.
- Avoid using corded electrical devices and plumbing during lightning.
- Secure outdoor furniture and other loose items if it is safe to do so.
- Never drive through flooded roadways. Turn around, don't drown.
How can I stay informed?
The National Weather Service recommends using multiple ways to receive weather alerts, including:
- Wireless Emergency Alerts on your smartphone
- Local television and radio stations
- NOAA Weather Radio
- The National Weather Service website and forecast updates
