Driving too fast for the road conditions could be a problem Wednesday throughout the day and into the evening.
A band of steady snow crossed parts of the region in the morning, powered by a strong south-southwest wind.
Visibility for drivers is poor at times because of blowing snow. Roads have become snowcovered, snow-packed and snow is drifting in some spots.
The snowfall will ease through the afternoon, but the strong wind won't diminish until Monday evening. Afternoon driving conditions could be poor in places.
The OPP is reminding drivers to use their full set of headlights because daytime running lights are not as bright and do not engage your rear taillights, making it difficult for drivers to see the vehicle from behind.
A blast of Arctic air late Thursday is expected to trigger lake-effect snow, and isolated snow squalls. Blowing snow and squalls are forecast to continue into Friday.
Snowfall totals are predicted to be in the range of 10-15 cm, but there could be higher amounts of squalls. Wind chill values overnight Thursday and Friday could feel closer to -20C.
