Schools across much of Newfoundland's Avalon Peninsula closed Thursday, as snowy weather caused treacherous road conditions.

The storm was strong enough to prompt some banks in the St. John's area to also close, at least for the morning.

While the storm was not expected to break snowfall records, it caused difficult driving conditions around the region, with gusts of wind cutting down on visibility.

The Trans-Canada Highway and major arterials in the region were snow-covered and slippery. Police urged drivers in the area around Avondale to "drive with extreme caution."

CBC reporter Cecil Haire said he was receiving reports from across the region of cars and trucks becoming stuck in the snow.

Metrobus altered some of its routes in St. John's to avoid steep hills.

According to CBC meteorologist Ryan Snoddon, the metro area is looking at six to 12 centimetres of snow by early Thursday afternoon, with 12 to 18 centimetres expected for the southern Avalon Peninsula.
