Yellow Alert: Lake Effect Snow in Rochester, NY

Why this matters: The lake effect snow can significantly impact travel and daily activities. Residents should be prepared for slick road conditions and reduced visibility.

The lake effect snow is being driven by cold air moving across Lake Ontario. The band of snow is expected to shift around at times, potentially impacting the immediate Rochester area, especially during the morning commute. While some areas may experience blue skies and sunshine, blustery and cold conditions are expected throughout the region. Another cold front is expected over the weekend, potentially bringing more lake effect snow on Sunday, though accumulation is expected to be minor. There is also the potential for a storm along the east coast that could bring snow to the Buffalo Bills game at New England on Sunday.

How to prepare: Check local forecasts before traveling. Allow extra time for your commute and drive cautiously in snowy conditions. Be aware of blowing snow and reduced visibility. Dress warmly in layers to protect against the cold.

Lake effect snow is produced when cold air passes over relatively warm lake water. The warm water heats the lower layer of air, which picks up moisture and rises, forming clouds and leading to snow.

Areas north of Route 104 and into Wayne County are expected to be most heavily impacted.
