A Watch means "be ready.": Conditions are favorable for severe weather to develop, but hazardous weather is not yet occurring. Watches cover large areas and give you time to prepare.
A Warning means "take action now.": Severe weather is occurring or is imminent in the warned area. Warnings cover smaller areas and indicate an immediate threat to life or property.
Why this matters:: Misunderstanding these terms can lead to complacency during a warning or unnecessary panic during a watch. Knowing the distinction helps New Yorkers respond appropriately.
Current situation:: As of July 21, 2026, the Flash Flood Warning for Southern Westchester County has been canceled, but a Flood Watch remains in effect until 2:00 AM EDT Wednesday, July 22.
Historical context:: New York has experienced significant flash flooding events in recent years, particularly in urban areas where drainage systems can be overwhelmed during heavy downpours.
A watch is issued by the National Weather Service when conditions are favorable for severe weather — such as thunderstorms, tornadoes, or flooding — to develop. Watches are typically issued hours in advance and cover a broad geographic area, sometimes spanning multiple counties or states.
During a watch, you should:
Monitor the latest forecasts and weather alerts via NOAA Weather Radio, local TV, or smartphone alerts.
Review your emergency plan and identify safe locations in your home.
Be prepared to move to a safe location if conditions worsen.
Ensure you have a way to receive warnings, such as Wireless Emergency Alerts (WEA) on your smartphone.
A warning means severe weather is occurring or is expected to occur very soon. Warnings are issued for much smaller, targeted areas — often a single county or portion of a county — and indicate an immediate threat to life and property.
What to do during a tornado warning:
Move immediately to a basement or an interior room on the lowest floor of a sturdy building.
Stay away from windows and exterior walls.
Protect yourself with a mattress, blankets, or a helmet.
If you are in a mobile home, leave it and seek shelter in a sturdy building.
If you are outside or in a vehicle, go to the nearest substantial building. Do not take shelter under a highway overpass.
What to do during a severe thunderstorm warning:
Move indoors and stay away from windows.
Avoid using corded electrical devices and plumbing during lightning.
Secure outdoor furniture and loose items if safe to do so.
Never drive through flooded roadways — Turn Around, Don't Drown.
As of July 21, 2026, the NWS New York office reported that the Flash Flood Warning for Southern Westchester County has been canceled. Flooding is no longer expected to pose a threat in that area, though residents are urged to continue heeding remaining road closures. A Flood Watch remains in effect until 2:00 AM EDT Wednesday, July 22, for portions of southern Connecticut and southeast New York.
Who this affects most: Residents in low-lying areas, those living near rivers and streams, and commuters who travel through flood-prone roadways in Westchester County and surrounding regions.
What is the difference between a Flood Watch and a Flood Warning?
A Flood Watch means flooding is possible — conditions are favorable for flooding to occur. A Flood Warning means flooding is already occurring or will occur soon, and you should take immediate action.
How can I receive weather alerts in New York?
The National Weather Service recommends using multiple alert methods: Wireless Emergency Alerts on your smartphone, local TV and radio stations, NOAA Weather Radio, and the NWS website.
Should I drive during a Flash Flood Warning?
No. Never drive through flooded roadways. Just six inches of moving water can knock a person down, and one foot of water can sweep a vehicle away. Turn Around, Don't Drown.
How long do watches and warnings typically last?
Watches can last for several hours or even a full day. Warnings are shorter — typically 30 minutes to an hour for tornado warnings, and a few hours for flood warnings, depending on the event.
Know the lingo:: A watch means prepare; a warning means act. This simple distinction can save precious minutes during an emergency.
Stay informed:: Use multiple sources for weather alerts — smartphone alerts, NOAA Weather Radio, and local news. Don't rely on just one method.
Have a plan:: Identify safe rooms in your home, know your evacuation routes, and keep an emergency kit ready.
Respect floodwaters:: Never drive or walk through floodwaters. Most flood-related deaths occur in vehicles.
Check current conditions:: As of July 21, 2026, the Flood Watch for southeast New York remains active. Stay updated through the [National Weather Service](https://www.weather.gov?ref=yanuki.com).
