Ottawa Public Health has issued a frostbite warning as Thursday's daytime high of –10 C will give way to a cold air mass cycling in from the northwest beginning Thursday evening.

Overnight lows will feel like –35 with the windchill, the public health agency warns.

They are asking people to wear several layers of clothing and monitor for the white waxy patches developing on your skin.

If you happen to suffer from frostbite or frostnip, never rub or massage the affected areas, Ottawa Public Health advises. You can warm up the skin gradually with water or body heat

Daytime highs in the –20 C range stick around through the weekend before things warm up Monday and Tuesday. 

The cold snap has also prompted Environment Canada to issue another cold weather warning.
