Cold Weather Alert

Very cold temperatures combine with strong winds will create wind chill values of minus 40 to minus 45 overnight tonight and Saturday morning. Conditions will improve later Saturday morning as temperatures rise in the northweatern regions. However, wind chill values of minus 40 to minus 45 will occur again Saturday night for some areas in northeastern regions.

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.
