Lake Effect Snow: Central NY Alert

Central New York residents need to be prepared. Lake-effect snow is a significant weather phenomenon impacting our region, often bringing heavy snowfall and challenging travel conditions. This article will provide crucial information to help you stay safe and informed during these intense weather events.

Understanding Lake-Effect Snow

Lake-effect snow occurs when cold, dry air masses move over relatively warm lake waters. This causes the lower layers of air to pick up moisture and warmth. As this air mass rises over the land on the downwind shore, it cools and condenses, forming clouds and producing significant snowfall. The effect is amplified by several factors, including:

• Temperature Difference: A larger difference between the lake water temperature and the air temperature leads to more intense snowfall.
• Wind Direction: The prevailing wind direction dictates which areas will experience the heaviest snowfall. Central New York's location relative to Lake Ontario makes it particularly vulnerable.
• Lake Size and Fetch: Larger lakes with long stretches of open water (fetch) allow for greater moisture pickup, resulting in heavier snow accumulations.

Central NY's Vulnerability

Central New York's proximity to Lake Ontario makes it a prime location for experiencing significant lake-effect snow. Areas east of the lake, particularly in the Tug Hill Plateau region, are notorious for receiving extremely high snowfall totals during lake-effect events. This is due to the topographic features that enhance the lifting and cooling of the moist air.

Staying Safe During Lake-Effect Snow

Preparation is key to staying safe during a lake-effect snow event. Here’s what you should do:

Before the Storm:

• Monitor Weather Forecasts: Pay close attention to weather alerts and advisories issued by the National Weather Service (NWS). Be aware of snowfall predictions, wind chill warnings, and travel advisories.
• Stock Up on Supplies: Gather essential supplies, including food, water, medications, flashlights, batteries, and a first-aid kit. Ensure you have enough fuel for your generator if you have one.
• Prepare Your Vehicle: Check your tire pressure, ensure you have adequate windshield wiper fluid, and keep a winter emergency kit in your car, including blankets, extra clothing, a shovel, and jumper cables.
• Charge Devices: Make sure your cell phones and other electronic devices are fully charged.

During the Storm:

• Stay Indoors: Unless absolutely necessary, avoid traveling during heavy snowfall. Road conditions can rapidly deteriorate, and visibility will be severely limited.
• Limit Travel: If you must travel, inform someone of your route and estimated arrival time. Drive slowly and cautiously, increasing following distance.
• Conserve Energy: If a power outage occurs, conserve energy by limiting the use of electricity and appliances.
• Stay Warm: Dress in warm layers of clothing to protect yourself from the cold and wind chill.

After the Storm:

• Check on Neighbors: Check on elderly neighbors or those who may need assistance.
• Clear Snow Safely: When clearing snow, take breaks to avoid overexertion. Be mindful of potential hazards like ice.
• Report Power Outages: Contact your local utility company to report any power outages.

Knowing the Risks: The Impact of Lake-Effect Snow

Lake-effect snow can have a significant impact on Central New York, causing:

• Travel Disruptions: Road closures, flight cancellations, and school closures are common during heavy lake-effect snow events.
• Power Outages: Heavy snow accumulation can lead to downed power lines and widespread power outages.
• Property Damage: The weight of heavy snow can cause damage to roofs and trees.

Staying informed and prepared is crucial for navigating the challenges of lake-effect snow in Central New York. By following these guidelines, you can help ensure your safety and well-being during these intense winter weather events. Remember to check regularly for updates from reliable weather sources and heed all official warnings and advisories.
