John Reynolds, the Executive Director of the Stockton Shelter for the Homeless can predict how crowded his facilities will be on any given night just by checking the weather forecast.
"Anything below forty degrees and we know we're going to have a packed house".
At the men's shelter there are 140 beds, but this week with temperatures dipping to the freezing mark, the operators of the facility had to improvise to accommodate a surge in the homeless.
"We'll put them down on the floor, mats on the floor, blankets and pillows in a multi-purpose room, if they have absolutely nowhere to go."
Reynolds says no one is turned away.
Another facility for homeless families has also been filled this week. As is the case with the men's shelter, late arrivals slept on the floor.
