What Is a Lake Effect Snow Warning?

A lake effect snow warning serves as a critical alert. It issues when intense localized snowfall nears due to the unique lake effect snow event. This happens as frigid Arctic air masses flow over the warmer waters of the Great Lakes. Moisture evaporates and condenses fast into heavy snow squalls on land. These events create narrow, intense bands of snow. They dump feet in hours but spare areas miles away.

The National Weather Service (NWS) sets levels of severity. A Lake Effect Snow Warning signals life-threatening accumulations (typically 6+ inches in 12 hours). It requires immediate action. A watch means conditions favor snow within 24 to 48 hours. An advisory warns of lighter but hazardous snow (3 to 6 inches). Interactive NWS maps show these bands in real time. They offer pinpoint forecasts for cities like Buffalo, NY. Lake effect snow buries the region under 2 feet overnight. Stay ahead. Visit weather.gov for alerts tailored to your zip code.
