Snow Squall Warning

Issued at 05:26 Saturday 13 February 2016

Snow squalls have developed in the overnight hours to the southeast of Lake Huron. Strong northwest winds and heavy snow at times will reduce visibilities to near zero. The main snow squall is occurring from near Kettle Point to Glencoe with other squalls from Lambton Shores and Grand Bend to Strathroy. These heavy squalls should stay west of London until a little later today when winds shift slightly. Total snowfall amounts in excess of 30 cm are likely in a few locales just to the southeast of Lake Huron by this evening. Although lesser overall amounts can be expected in Elgin county, local poor driving conditions may be expected there due to poor visibility and accumulating snow. This is a dangerous situation especially because of very cold temperatures and wind chills in combination with the snow squalls. Several roads remain closed to the east of Lake Huron. Drivers should pay extra heed or delay travel if necessary to avoid being stranded on heavily snow-covered roads in the extreme cold. Prepare for quickly changing and deteriorating travel conditions. Travel is expected to be hazardous due to reduced visibility in some locations. 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. For information on emergency plans and kits go to Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities. 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 05:06 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. Very cold wind chill values between about minus 30 and minus 40 are occurring this morning, aided by bitterly cold northerly winds. Wind chill conditions will improve only marginally this afternoon, then fall below minus 30 again tonight in most locales. Some improvement is expected on Sunday as temperatures moderate somewhat. Milder weather will arrive on Family Day Monday with temperatures approaching normal values for this time of year. While anyone who isn't dressed warmly is at risk in cold weather conditions, some are at greater risk than others for frost bite and hypothermia: - homeless people - outdoor workers - people living in homes that are poorly insulated (with no heat or no power) - people with certain medical conditions such as diabetes, peripheral neuropathy and diseases affecting the blood vessels, people taking certain medications including beta-blockers - winter sport enthusiasts - people who consume excess alcohol - infants and - seniors. 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. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports to #ONStorm.
