Lake Effect Snowstorm Hits Ohio: Travel Warnings for Interstate 90

A Lake Effect Snow Warning has been issued by the National Weather Service (NWS) in Cleveland, effective from 3:48 AM EST Wednesday through 10:00 AM EST Saturday.

The warning predicts heavy snow accumulations and hazardous conditions in Ohio across Ashtabula Inland, Ashtabula Lakeshore, Geauga, and Lake Counties, Crawford, Northern Erie, Southern Erie.

The warning highlights significant travel impacts, especially along Interstate 90, with NWS reporting that conditions may make travel impossible at times. Those living or planning to move through the affected areas are advised to postpone any non-essential travel. Friday's morning and evening commutes could face major disruptions as snow and strong winds reduce visibility.

The NWS warning said: "Visibilities may drop below 1/4 mile due to falling and blowing snow. Travel is impossible and should be postponed. Areas of blowing snow could significantly reduce visibility. The hazardous conditions could impact the Friday morning and evening commutes and post-holiday travel, especially along Interstate 90."

Residents in the affected areas should prepare for snow accumulations of 10 to 28 inches, according to the NWS, with snowfall rates reaching one to two inches per hour in some regions. Winds gusting up to 35 mph near the lakeshore will contribute to dangerous conditions, with visibility potentially dropping to below a quarter of a mile due to blowing and falling snow.

Anyone who must travel is advised to keep an extra flashlight, food, and water in
their vehicle in case of an emergency.

"If travel is absolutely necessary, drive with extreme caution," said the NWS. "Consider taking a winter storm kit along with you, including such items as tire chains, booster cables, flashlight, shovel, blankets and extra clothing. Also take water, a first aid kit, and anything else that would help you survive in case you become stranded."

Meanwhile, a Lake Effect Snow Warning has been issued for St. Lawrence County, New York, with heavy snowfall expected to impact the region through Monday. Additionally, a Winter Weather Advisory is in effect for Franklin County as the region braces for severe weather conditions.

A Lake Effect Snow Warning is a weather alert issued when significant snowfall is expected due to the meteorological phenomenon known as lake effect snow. This occurs when cold air moves over a large, warmer body of water, like the Great Lakes. The contrast between the cold air and the relatively warmer lake water causes moisture to evaporate, which then condenses into snow.

In a Lake Effect Snow Warning, the NWS is warning that conditions are expected to bring heavy snow accumulation and potentially hazardous travel conditions, often over a short distance. The warning typically applies to areas directly downwind of the lake, where the snowbands are most concentrated. The warning means that the snow will be intense, and travel could be dangerous due to low visibility, slick roads, and high snow accumulation.
