Environment Canada has issued an extreme cold warning for the City of Hamilton.

Frigid temperatures are on their way as a cold front moves into Southern Ontario tonight and Wednesday.

Strong, northerly winds will bring temperatures to the -17 mark by Wednesday afternoon but it will feel more like -30 with the wind chill.

If you don’t need to spend that much time outside it’s a good day to spend indoors. - Geoff Coulson, Meteorologist, Environment Canada

Environment Canada is warning anyone who isn't dressed warmly is at risk for frost bite and hypothermia.

Geoff Coulson, Meteorologist for Environment Canada says colder than normal temperatures will remain throughout the week and into the weekend. Normal temperatures for this time of year are -2 during the day and around -9 overnight.

Dan Millar, director of public relations for the Salvation Army, says the public can report someone in need of shelter by calling Hamilton’s cold weather hotline at 905-527-1444 ext 224.

The Salvation Army works alongside other agencies in the city to ensure that residents are safe during the extreme cold.

“There is a lot of concern so that’s why we are out there right away to try and bring everyone inside,” said Millar.

There is a response van providing blankets and warm clothing for the homeless, he said.

Being prepared

Jackie Penman, Manager of Corporate Communications for the Hamilton Wentworth District School Board said in an email that it’s important for students to arrive at school dressed and prepared for the cold weather. She said principals use discretion in determining whether or not students remain inside during recess given the extreme weather conditions.

Environment Canada is advising residents to dress appropriately with layers for additional insulation and is also recommending that drivers have a roadside emergency kit including a blanket and extra winter clothing in the event of getting stranded.

“If you don’t need to spend that much time outside it’s a good day to spend indoors,” said Coulson.

The Hamilton Fire Department is also urging the public to keep fire safety in mind when dealing with snow and cold winter weather.

The winter months often see more fires in homes, related to heating equipment and appliances. Residents should pay close attention when using fuel-burning appliances, space heaters and block heaters in vehicles, as all are potential fire hazards.
