Extreme Cold Warning

Issued at 5:04 a.m. EST Monday 29 December 2014
Summary

A period of very cold wind chills is expected. A very cold Arctic air mass has become established across Northwestern Ontario. Northwest winds of 10 to 20 km/h are combining with low temperatures near minus 30 to produce extreme wind chill values near minus 40 this morning. After a temporary improvement of wind chills under mainly sunny skies this afternoon, extreme cold wind chills near minus 40 are expected to return again tonight into Tuesday morning. People outdoors should dress appropriately as frost bite on exposed skin may occur in a few minutes.

Details

Watch for cold related symptoms and complaints which include: - Respiratory: shortness of breath, wheezing and cough - Cardiovascular: chest pain and arrhythmias - Circulation: colour change of finger and toes, pain, numbness and tickling sensation in extremities - Muscle: pain, stiffness, swelling, restricted movement, weakness - Skin: itching, pale. If you experience these symptoms when exposed to the cold, move indoors and begin warming. Wear appropriate clothing. - Always wear clothing appropriate for the weather. Synthetic and wool fabrics provide better insulation. Some synthetic fabrics are designed to keep perspiration away from your body which keep you dry and further reduce your risk. - Dress in layers with a wind resistant outer layer. You can remove layers if you get too warm (before you start sweating) or add a layer if you get cold. - Wear warm socks, gloves, a hat and scarf in cold weather. Be sure to cover your nose to protect it. - If you get wet, change into dry clothing as soon as possible. You lose heat faster when you're wet. Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia. Environment Canada meteorologists will update alerts as required, so stay tuned to your local media or Weatheradio.
