A warming center is a place that people can go to when it's very cold outside and they don't have a warm place to stay. It's like a big indoor blanket that keeps people safe and warm.
Sometimes the weather can be so cold that it's dangerous to be outside for too long. People can get really sick or hurt if they don't stay warm enough. When this happens, a warming center can be opened up.
A warming center has lots of blankets, chairs, and warm drinks to help people stay cozy. There are also people there who can help take care of others, like nurses or volunteers. Anyone who needs a warm place to stay can go to a warming center, no matter who they are or where they come from.
Warming centers are usually open only for a short time, like one night or a few days. They are meant to be a safe place to stay until the weather gets better and it's safe to be outside again.
