Weather Network advisory calls for hazardous, potentially life-threatening travel conditions

The possibility of snow squalls combined with freezing Arctic air make the next couple of days a dangerous time to be driving on Highway 401 west of London, says The Weather Network.

As of Thursday morning, meteorologist Michael Carter warned of “extremely hazardous and potentially life-threatening travel conditions” across parts of southwestern Ontario.

While the Great Lakes region continues to experience its coldest temperatures of the season, “lake effect” snow squalls have been developing off of Lake Huron.

Carter said areas south of Grand Bend will be hardest hit by this band of snow squalls — but the band will also reach down to the 401 west of London. Motorists should beware of “extended periods of whiteout conditions and roads likely becoming impassable.”

“The band will also shift into the city of London at times,” Carter predicted.

The conditions are expected to continue through Friday and into Saturday before easing on Sunday.

The Weather Network’s forecast came at the same time as a special weather statement by Environment Canada for all of Southern Ontario, including Windsor-Essex, advising of bitter cold throughout Friday and into Saturday.

As of Thursday morning, Environment Canada predicted that thermometers at Windsor Airport won’t get higher than -16 C on Friday. When night falls, the mercury will plummet to -22 C.

With the wind chill factor, being outdoors will feel like -30 C for Windsor-Essex residents.

“This dangerous cold coupled with heavy snowfall will create life-threatening conditions for stranded drivers on some of southern Ontario’s biggest travel corridors,” Carter wrote.

The Windsor-Essex County Health Unit advises that motorists should prepare for the eventuality of being stuck in winter weather. Vehicles should be stocked with: a shovel gravel or sand a sleeping bag or blanket candles matches extra socks mittens, gloves and warm headwear

a brightly-coloured cloth or flag large enough to signal for help

Should you become stranded in your vehicle not in walking distance of shelter, the health unit advises:

Remain calm. Phone for help and do not leave your vehicle until assistance arrives.

Tie your brightly-coloured cloth or distress flag to a side mirror.

Stay warm. Remove wet clothing. Wrap yourself in your sleeping bag or blanket.

If the vehicle has two or more occupants, sit together in the back seat to share body heat.

Only run your motor if necessary. Keep a window slightly open to prevent carbon monoxide buildup.
