What is a Lake Effect Snow Warning?
A Lake Effect Snow Warning is a weather alert issued by the National Weather Service when heavy snowfalls are expected to occur due to lake effect conditions. These conditions arise when cold air masses move over warmer lake waters, picking up moisture and depositing it as snow over land. This phenomenon typically affects areas located downwind of large lakes, creating localized, intense snow bands that can lead to rapidly changing weather conditions.
When is it Issued?
This warning is typically issued when snow accumulations are expected to meet or exceed warning criteria within a 12 to 24-hour period. The criteria can vary based on the region but generally involve several inches of snow within a short timeframe, coupled with reduced visibility and hazardous travel conditions.
How to Prepare for a Lake Effect Snow Warning
Preparation is key to ensuring safety during a Lake Effect Snow event. It's crucial to stay informed by monitoring local weather updates and heeding advice from weather authorities. Ensure that you have an emergency kit ready, including essentials such as food, water, blankets, and a first-aid kit. If travel is necessary, keep a full tank of gas, and carry winter gear in your vehicle, such as an ice scraper, shovel, and extra clothing. Additionally, check that your home is equipped to handle heavy snow, such as having proper insulation and ensuring heating systems are working efficiently.
Impact of Lake Effect Snow
The impact of lake effect snow can be severe, with potential disruptions to daily life including school closures, road blockages, and power outages. Visibility can be significantly reduced, making travel extremely dangerous. It is advisable to avoid unnecessary travel and stay indoors until conditions improve. Being prepared and staying informed can help mitigate the risks associated with Lake Effect Snow Warnings.
