Lambton’s Medical Officer of Health has issued a  cold weather alert for Sarnia-Lambton.

The latest weather forecast from Environment Canada predicts the daily, low air temperature will drop below -16°C this afternoon and -25°C tonight. The cold alert will remain in effect throughout the week until Friday morning.

It is expected to be very cold with severe wind chill values over the next few days.

Residents should take precautions during a Cold Weather Alert by dressing in layers, shielding exposed areas from the wind such as head, neck and face, and limiting time spent outdoors.

Overexposure to cold can be hazardous, even life-threatening. Hypothermia, which can strike in any season, occurs when the body temperature drops below the normal range. Symptoms may include pale skin, lethargy, confusion, excessive shivering and hallucinations. People with hypothermia should be brought to a doctor.

Frostbite can occur in skin that is overexposed to cold temperatures. Symptoms of frostbite include skin turning red, blue, or a grey/white colour. You may also experience pain, numbness and stiffness, especially in fingers, toes, ears and nose.

If you suspect frostbite:

• Warm the skin next to the affected area or immerse in warm water. Do not use hot water.
• Do not rub the affected area.
• Seek immediate medical help.
• Re-warming may take up to 60 minutes.
