THUNDER BAY – WEATHER – Almost all of Northwestern Ontario is under Extreme Cold Warnings. The Arctic cold has made its way through the region.
Only the very southern parts of the region are not under the warnings issued by Environment Canada.
A prolonged period of very cold wind chills is expected.
Very cold Arctic air combined with light winds will produce cold wind chill values. Very cold wind chill values near minus 40 are expected tonight into Sunday morning. Some regions may see these cold wind chill values again Sunday night into Monday morning.
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.
– Consuming alcohol before you go out in the cold may increase your risk of hypothermia because it increases blood flow to the extremities of the body. You may actually feel warm even though you are losing heat.
Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
