Snow Squall Warning

Issued at 21:49 Saturday 13 February 2016

Flurries and localized snow squalls are occurring to the south of Georgian Bay as bitterly cold arctic air continues to get ushered in by stiff northerly winds. The strongest lake effect snow band extends from near Meaford across Blue Mountain and Collingwood then inland across Creemore area. Additional snowfall amounts of 5 to 10 cm are likely tonight in the strongest snow squalls. Some blowing snow is expected in exposed areas. Motorists should allow extra time to reach their destination. Visibility may suddenly be reduced to near zero in bursts of heavy snow and blowing snow in exposed areas. The lake effect snow bands are forecast to slowly weaken late this evening, thanks to diminishing winds and a huge cold arctic high pressure area moving in from the west. 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. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop. Rapidly accumulating snow could make travel difficult over some locations. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports to #ONStorm.


Extreme Cold Warning

Issued at 17:19 Saturday 13 February 2016

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 or tweet reports to #ONStorm.
