A "Snow Advisory" is a weather alert issued by meteorological agencies to inform the public about expected snowfall that may impact travel and outdoor activities. This advisory typically indicates that snow accumulation could reach a certain amount, often between 1 to 4 inches, within a specified time frame. During a Snow Advisory, it is important for individuals to stay updated on weather conditions and prepare for potentially hazardous situations, such as slippery roads and reduced visibility. Local authorities may recommend avoiding unnecessary travel and taking precautions to ensure safety during winter weather events.
