Environment Canada has issued a special weather statement for Sarnia-Lambton.
Actual snowfall amounts will likely be limited to 5 cm or less. Low visibility at times in brief bursts of heavier snow and local blowing snow will result in poor winter driving conditions into this afternoon.
Motorists should exercise caution and allow extra time to reach their destination as a result.
OPP closed the westbound Hwy. 402 for close to three hours this morning between Hickory Dr. and Centre Rd in the Strathroy area due to several collisions and white out conditions. The highway has since reopened.
