City issues cold weather alert as Hamilton temperatures plunge

The city has issued a cold alert effective Friday night, as frigid temperatures are set to hit Hamilton once again.

Cold weather alerts are issued when current or expected weather conditions are at or below -15 C, or -20 with the wind chill.

Tonight's forecast is calling for a low of -16 C, with wind chill values making it feel like -25 overnight.

Environment Canada is warning there is a risk of frostbite.

The city is advising people to check on vulnerable family, friends and neighbours during the cold alert.

Officials are advising people to stay indoors, but if you have to be outside:

• Dress in layers of clothing. Keep inner layers dry. Wet clothing increases the risk of cold injury.
• Protect your face, ears and hands with a scarf, hat, and gloves
• To protect your feet, socks must be dry. Wool is a good material to keep your feet dry.
• Drink warm fluids, but avoid caffeine and alcohol
• Avoid strenuous exercise
