Environment Canada has issued a Winter weather alert for Oakville on December 10, 2017 at 4:07 PM. The severe weather is expected to start on later Monday afternoon December 11 to late Tuesday evening, December 12, 2017, according to the Weather Channel.

Anticipated snowfall is 10 to 15 cm. The heaviest snow is forecast to begin late Monday evening, December 11 and end early Tuesday morning, December 12. Anything above 15 cm over 12 hours is a snowfall warning, which is not expected.

This is the first winter weather event update issued by Environment Canada since the winter storm alert for Monday, March 13, 2017.

Winter establishes a firm grip on Southern Ontario.

An Arctic cold front will cross Southern Ontario this evening. It will likely be accompanied by a brief burst of heavier snow in many areas with reduced visibilities which may affect travel. A coating to a couple of centimetres of the white stuff in a short timeframe is expected with this cold front this evening.
