The 60-year-old said: “We’ve started doing an extra three outreaches per night to run alongside the five we already do.”
Kathryn Wright, 41, is a volunteer for the group after she had been homeless in the past.
“It is really horrible,” she said, adding that she “hated” sleeping rough.
She said she was helped by the Booth Centre and the Don’t Walk Past group which had inspired her to help others.
“I feel sorry for them which is why I volunteer with Ronny,” she said.
Glenn, 51, who is homeless, said he was taking shelter wherever he could to keep out of the cold.
“I don’t mind the snow but the rain when it is really cold is the worst because it is getting dry afterwards,” he said.
“The last few days… has been really bad because even in the built up areas it is icy all the time so if you get wet you’re in danger.”
Manchester City Council said it was “working hard” with other organisations, which made up the city’s Homeless Partnership to address the issue.
Midgley said: “In Manchester, the overall number of people sleeping rough is relatively stable”, but she added that one person sleeping rough was “too many”.
