Snow Squall Warning

Issued at 21:58 Saturday 13 February 2016
Summary

Snow squalls continue to come in off of Lake Huron. Strong northwest winds and heavy snow at times will reduce visibilities to near zero. The strongest lake effect snow bands are coming ashore between Bayfield and Kettle point, and are extending inland across London to the Harrietsville area. Further snowfall amounts of 10 to 15 cm are quite likely in the strongest lake effect snow bands tonight. Latest indications suggest the strongest lake effect snow bands may try to start drifting back to the west of London beginning later this evening. This remains a dangerous situation especially because of very cold temperatures and wind chills in combination with the snow squalls. Parts of Highway 21 near Lake Huron remain closed. Drivers should pay extra heed or delay travel if necessary to avoid being stranded on heavily snow-covered roads in the extreme cold. Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Travel is expected to be hazardous due to reduced visibility in some locations. Be prepared to adjust your driving with changing road conditions. Consider postponing non-essential travel until conditions improve. Road closures are possible. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to storm.ontario@ec.gc.ca or tweet reports to #ONStorm.

Extreme Cold Warning

Issued at 17:19 Saturday 13 February 2016
Summary

A period of very cold wind chills is expected. The coldest air of the season has settled across Southern Ontario for the weekend as a large arctic high pressure area settles in over the Great Lakes. Extremely cold wind chills of between minus 30 to minus 40 are once again expected later tonight into Sunday morning as bitterly cold arctic air continues to be ushered in by north to northwest winds. Slow improvement of the wind chills is expected on Valentine's Day afternoon as the strengthening February sun helps to moderate this frigid arctic airmass, with temperatures inching upward a few degrees. Considerably milder weather will arrive on Family Day Monday with temperatures approaching normal values for this time of year. 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. Avoid alcohol. - 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. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to storm.ontario@ec.gc.ca or tweet reports to #ONStorm.
