The City of Hamilton has issued a Cold Weather Alert for Wednesday night.
It’s a result of wind chill values that are expected to push the temperature below minus 20.
The forecast low is -13, but that is before wind gusts of 40 kilometres per hour are factored in.
The City of Hamilton has notified community agencies who work with vulnerable and homeless people.
Each of those agencies, including Salvation Army, will implement their policies and procedures with regards to cold weather.
