The Salvation Army shelter in north Charlotte implemented their "no turn-away policy" Thursday morning because of the high temperatures.
The shelter says it's also dealing with overcrowding issues.
Before this week, Rosalee Rodriguez had been living anywhere she could rent a room, including hotels, but the cost simply became more than she could manage.
"We can't come up with that kind of income just like that," Rodriguez said.
For the last week, she has been one of hundreds of women who have called the Salvation Army shelter home, and because of the heat, more women like her need a place to stay.
Director of social services for the Salvation Army, Deronda Metz, said the charity has room for a little more than 220 beds. They are expecting about 300 people at the shelter Thursday night.
"We have a lot of families in homelessness right now. So we definitely don't want to have our moms and kids on the street," Metz said.
That means TV rooms in the shelter have been cleared out for cots to serve as temporary bedrooms.
Metz says organizers are working on a solution.
A new program in Charlotte called Rapid Rehousing is using private donations to move families from the shelter to more long-term housing.
Right now, Metz said there about 13 families in the program. They hope to have 30 or 40 by the time school starts.
"If we could move about 100 families out of this shelter in one year’s time, we really won't be talking about overcrowded shelters when the weather is hot, cold or just on the typical day," Metz said.
Metz said they typically see an increase in the number of people shortly after school lets out for the summer. She said that, combined with the higher temperatures, is the reason it's important to find a better solution.
