Update 10 p.m.: The snow squall watch has ended for SD&G.
SD&G – Heavy bursts of snow, coupled with brisk winds, could make for some white-knuckle driving tonight (Thursday).
Environment Canada has issued a snow squall watch for SD&G.
As a cold front passes through the region this evening, there could be whiteout conditions as 2-4 centimeters (1-2 inches) of snow falls. The wind is expected to shift to the northwest at 30 kilometers an hour gusting to 50 at times.
The weather forecasters say the weather conditions could vary a lot tonight and travel may be hazardous due to sudden changes in the weather.
Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
The weather should clear up overnight with sun and clouds for Friday.
