With temperatures at that freezing mark, some local homeless shelters have put out the white flag.
This means they make room for everyone to spend the night.
The United Caring Shelters in downtown Evansville says the white flag represents an "open door policy."
They put it out anytime it's going to be below freezing for three hours or more.
This means anyone can come inside and get out of the cold between 7pm and 7am.
The UCS says they've hosted 14 white flag nights so far this winter.
With some cold nights ahead, they plan to keep the flag out until at least January 2.
They average about 15-20 people, ranging from men, women and children.
And they won't turn anyone away.
They make room for extra people in the main room, pushing dining tables to the side and setting up cots.
With more people coming in, expenses like utilities and food costs increase.
Guests sometimes pitch in to prepare meals when they're short on volunteers.
You can help the shelter by donating money or time.
