There is an extreme cold warning in effect for our area meaning that windburn, frostbite and hypothermia can set in quickly. There are four signs of frostbite, health officials call them the four “P’s:” a pink or reddish in colour of the skin, which is the first sign. Pain, your skin becomes painful. Patches, white, waxy-feeling patches will show when your skin is dying. And finally, the Pricklies as affected areas become numb. You should seek immediate medical attention if you see white or grey coloured patches or if the area is numb. Temperatures below -40 C can cause frostbite within 10 minutes.
