Lake-Effect Snow Buries Great Lakes Region, Triggering State of Emergency
The Great Lakes region in the United States is being battered by an intense snowstorm, forcing officials to declare a state of emergency in New York. This meteorological event, known as a “lake-effect” snowstorm is impacting a seven states, primarily affecting cities like Buffalo in New York, which have been buried under several feet of snow.

This massive system is the result of frigid air flowing over the relatively warmer waters of the Great Lakes.
This process triggers evaporation leading to heavy snowfall. Buffalo is experiencing its worst lake-effect snowstorm since November 2014.

What meteorological conditions are necessary for lake-effect snow to occur?
## Lake-Effect Snow Blankets Great Lakes Region
**INTRO MUSIC**
**ANCHOR:** Welcome back. As much of the country braces for winter weather, the Great Lakes region is getting slammed by a powerful lake-effect snowstorm. Joining us now to discuss this phenomenon is meteorologist Dr. Emily Carter. Dr. Carter, what exactly is fueling this intense snowfall?
**DR. CARTER:** Thanks for having me. This heavy snowfall is a result of what we call lake-effect snow. It occurs when cold, dry air passes over the relatively warm waters of the Great Lakes. The air picks up moisture and heat, rises rapidly, and then cools, causing the moisture to condense and form heavy snow bands downwind of the lakes.
**ANCHOR:** So, it’s essentially a perfect storm of meteorological conditions.
**DR. CARTER:** You could say that. You need a combination of cold air, open water, and wind direction for lake-effect snow to develop. This particular storm system is drawing cold arctic air from the north over the relatively warmer Great Lakes, and the wind direction is favoring heavy snowfall in certain areas.
**ANCHOR:** We’re seeing some truly staggering snowfall totals. Can you give us an idea of how much snow we’re talking about?
**DR. CARTER:** Some areas downwind of Lake Erie and Lake Ontario have already seen several feet of snow, and accumulations could reach well over five feet in some locations by the end of the storm. [1](https://weather.com/storms/winter/video/lake-effect-snow-explained-0)
**ANCHOR:** That’s incredible. Are there any particular precautions people in the affected areas should be taking?
**DR. CARTER:** Absolutely. People should avoid unnecessary travel as road conditions are extremely dangerous. High winds are also creating blowing and drifting snow, further reducing visibility. It’s crucial to stay informed about weather updates and follow local authorities’ recommendations.
**ANCHOR:** Well, Dr. Carter, thank you so much for breaking down this weather phenomenon for us. Stay safe out there everyone!
