Numerous schools across eastern Newfoundland closed for at least the morning Wednesday as road conditions rapidly deteriorated in heavy snow.

Schools in areas like the Burin Peninsula and Conception Bay closed after several centimetres of snow fell over a short period of time, making driving unsafe on many roads and regional highways. 

Schools in metro St. John's stayed open, although the weather — including about five centimetres of snow that made roads greasy — caused accidents and prompted safety warnings. 

Messy system on way

Meanwhile, much of Newfoundland and Labrador was under a weather warning, the result of a messy system that will move in Wednesday evening and last until Sunday. 

Environment Canada said it will involve snow, rain, freezing rain and strong winds. 

While western Newfoundland has been warned to expect snow, southern regions of Newfoundland have been put on alert for rain that could total 15 mm by Thursday night. 

"The rain combined with warm temperatures will cause significant snow melt, which could lead to localized flooding," an Environment Canada warning said.
