A lake-effect snow warning has been issued for Erie County starting early Monday. This warning is due to a substantial multiday lake-effect snowstorm set to intensify. Some parts of western New York could pick up well over a foot of snow where the heaviest lake-effect snow bands set up.
Lake-effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow bands that produce 2 to 3 inches of snow per hour or more.
Please stay safe and take necessary precautions if you are in the affected area.
Safety measures during lake-effect snow
Here are some safety measures advised during lake-effect snow conditions:
- Slow Down: It’s essential to reduce speed while driving in these conditions.
- Increase Following Distance: This can help prevent accidents due to sudden stops.
- Ensure Proper Vehicle Equipment: Make sure your vehicle is equipped with proper tires and safety equipment.
- Stay Updated on Weather Forecasts and Road Conditions: This can help you prepare for any sudden changes in weather.
- Prepare Essential Supplies: Make sure homes, offices, and vehicles are stocked with essential supplies. This can include flashlights and extra batteries, food and water, first-aid supplies, heating fuel, and emergency heat sources.
- Find Shelter During a Snowstorm: If you’re outside during a lake-effect snowstorm, quickly find shelter.
- Ensure Safety on the Roads: If you begin to skid while driving, remain calm, ease your foot off the gas, and turn your wheels in the direction you want the front of the car to go.
- Pull Over if Visibility is Poor: If you’re having trouble seeing due to weather conditions, pull over to the side of the road and stop your car until visibility improves.
- Stay Visible to Rescuers if Stuck: If your car gets stuck during a storm, remain in the vehicle and be visible to rescuers.
- Stay Informed After a Storm: After a storm hits, stay informed on local closures and road conditions.
Remember, it’s always important to exercise caution and follow weather advisories during lake-effect snow events.

winter weather patterns in western New York
Winter weather patterns in Western New York are influenced by a variety of factors. One of the key factors is the presence of the Great Lakes, which can lead to lake-effect snow. This occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow bands that produce 2 to 3 inches of snow per hour or more.
Another factor that can influence the winter weather patterns in Western New York is the El Nino Southern Oscillation (ENSO). This is a climate pattern that involves changes in the temperature of waters in the central and eastern tropical Pacific Ocean. On periods ranging from about three to seven years, the surface waters across a large swath of the tropical Pacific Ocean warm or cool by anywhere from 1°C to 3°C, compared to normal.
The National Oceanic and Atmospheric Administration (NOAA) releases their winter weather outlook each year, which provides an overview of what the winter weather could look like in Western New York. This outlook takes into account various factors including ENSO conditions, sea surface temperatures, and statistical models.
It’s important to note that weather patterns can vary from year to year, and even from day to day, so it’s always a good idea to check the latest weather forecasts for the most accurate and up-to-date information.
