The Middlesex-London Health Unit (MLHU) has extended its cold weather alert.

Windchill values are expected to drop to a chilly -22 C overnight, improving slightly to -20 C in the morning and -16 C in the afternoon across London and Middlesex County.

A snow squall warning remains in effect for parts of the region on Wednesday.

Lake effect squalls continue bringing reduced visibility that could be heavy at times for parts of Huron, Perth and Oxford counties.

Steps to take during cold weather event

• Stay in heated buildings as much as possible (your home, friend or family’s place, public buildings such as malls, libraries, etc.)
• Dress appropriately when going outside (multiple layers of loose-fitting clothes, toques, mittens, etc.) and cover up all exposed skin since, in extreme cold, frostbite can occur within minutes
• Drink warm fluids but avoid caffeinated or alcoholic beverages, as they cause your body to lose heat more rapidly
• Avoid strenuous exercise while out in the cold as much as possible
• Know the weather forecast and avoid travelling when extreme weather is predicted
• Prepare your home and car for winter
