Lake Effect Snow Warning What You Need to Know for Safe Travel

Lake effect snow can create sudden and severe winter weather conditions, especially in areas near large lakes. Right now, a lake effect snow warning is in effect until 8 AM EDT Wednesday for Madison and Onondaga Counties. This warning means heavy snow, strong winds, and hazardous travel conditions are expected. If you live in or plan to travel through these areas, understanding what to expect and how to prepare can keep you safe.

What Is Lake Effect Snow?

Lake effect snow happens when cold air moves over warmer lake water, picking up moisture and heat. This air then cools as it moves over land, causing heavy snow showers in narrow bands. These snow bands can drop intense snowfall in some areas while nearby locations get little or no snow. This uneven pattern makes lake effect snow especially tricky for travelers and residents.

In this warning, the heaviest snow is expected along and north of Interstate 90, with snow accumulations between 6 and 12 inches. South of Interstate 90, snowfall will be lighter, around 1 to 4 inches. Winds gusting up to 35 mph will add to the challenge by reducing visibility and creating blowing snow.

Areas Most Affected

The warning covers Madison and Onondaga Counties, with the highest snowfall expected in the Clay, Cicero, and Brewerton areas. The City of Syracuse will see less snow, about 1 to 3 inches. The snow will be heaviest this evening through the overnight hours, with snowfall rates reaching 1 to 2 inches per hour at times.

Travelers should expect very difficult road conditions, especially during the Tuesday evening and Wednesday morning commutes. Roads may become slippery and visibility can drop quickly due to blowing snow.

How to Prepare for Lake Effect Snow

If you must travel during this warning, preparation is key. Here are some practical steps to stay safe:

• Check road conditions before you leave. Call 511 for the latest updates in your state.

• Keep an emergency kit in your vehicle. Include a flashlight, extra food, water, warm clothing, and a fully charged phone.

• Drive slowly and increase following distance. Snow and ice reduce traction and increase stopping distances.

• Be ready for sudden changes in visibility. Lake effect snow can cause visibility to drop from clear to near zero within minutes.

• Avoid unnecessary travel if possible. If you can delay your trip until after the snow tapers off around daybreak Wednesday, do so.

  
  

What to Expect During the Warning

The snow will start intensifying this evening and continue overnight. Expect localized heavy snow bands that can drop 1 to 2 inches per hour. Winds gusting up to 35 mph will cause blowing and drifting snow, making travel even more hazardous.

By early Wednesday morning, the snow will taper off to scattered snow showers and flurries. However, roads may remain slick and visibility poor during the morning commute.

Emergency services may be stretched thin during this time, so it’s important to drive carefully and be patient. If you get stuck or stranded, stay with your vehicle and call for help.

• Keep your gas tank at least half full to avoid running out of fuel if stuck.

• Use headlights in snow to improve visibility for yourself and others.

• Avoid sudden braking or sharp turns on snowy roads.

• Dress warmly and have blankets in your vehicle in case of emergency.
