Environment Canada issued an extreme cold warning for Peterborough County, Kawartha Lakes, northern Hastings County, and Haliburton County, beginning Thursday morning.
Late Wednesday afternoon, a cold front will push through the region, which will cause temperatures to abruptly drop below freezing.
By Thursday morning, cold temperatures in combination with brisk northwest winds will lead to wind chill values between -30°C and -35°C Thursday morning. Wind chill values are expected to moderate through the day Thursday, but may drop to near -30°C Thursday night into Friday morning once again.
Residents are encouraged to dress in layers if going outside is necessary.
It is also noted that surfaces such as highways, roads, walkways, and parking lots — especially untreated surfaces where snow has not yet been cleared — may become icy and slippery.
