Homeless shelters around Central Florida are getting ready to open their doors to people with no other way to escape the cold.

With temperatures set to drop into the 30s and wind chills near freezing overnight, the Orlando Union Rescue Mission is offering emergency shelter at its facilities in Orlando.

The men's shelters have 190 beds for emergencies, while the shelters for women and children have 70 beds available.

The Orlando Union Rescue Mission offers emergency shelter anytime temperatures are forecast to drop below 40 overnight.

The Coalition for the Homeless of Central Florida said it was not opening an emergency shelter Tuesday but will when temperatures reach the freezing point.

Meanwhile, other agencies said they are dealing with a shortage of winter supplies.

Molly Dorsey, who runs the Tiger Den at Orlando's Jones High School, got a call Tuesday that dozens of elementary school students were in need of coats.

"It's just a dire need here. We need it," Dorsey explained.

The Tiger Den collects clothing for students in need, and warm coats are among the biggest needs this week.

"It's cold, and they don't have any coats to put on," said Dorsey. "So, when they get there, they come to me and ask me, do I have a coat or a sweater and gloves, which I don't have right now."

The Coalition for the Homeless said it's also in need of coats, as well as blankets and gloves for people in need as chillier weather arrives.

With the cold weather also comes a reminder to stay healthy from our medical expert, Dr. Tim Hendrix of Centra Care, who says flu and cold season are already in full force.

"The cold weather puts an extra stress on our bodies. It puts a stress on our immune system," Dr. Hendrix explained. "Also, our airwaves dry out, which makes you more prone to viruses."

Now is a good time to get a flu shot, especially considering this time last season, we faced a shortage of the vaccine.

"We only seem to think about getting a flu shot when everyone around us is dropping like flies," Hendrix said. "But now is the time to prepare and get a flu shot."

Volunteers prepare Flagler County shelter

When it comes to offering shelter from the cold, there is no other place in Flagler County but the Sheltering Tree, a network of volunteers who open a cold weather shelter inside First United Methodist Church in Bunnell.

Pamela Andrews is a volunteer and she can't imagine being on the streets when it's even in the 50s and raining. “To be out there without a home, I couldn't imagine, so whatever we can do to give them a warm place to lay their head, that's all this is about.”

Carla Traister founded The Sheltering Tree. She said she gets requests for help daily.

“I have a list in the car of all the people that are asking for shelters, every single day, people call and ask for shelter," Traister said. "There is nothing in this county otherwise.”

While it will most likely be a full house inside this shelter, many of the people inside will not be from Flagler County.

About 20 cots will go to homeless from Volusia County, where shelters are beyond full when the weather turns cold.

They will come by bus and find open arms to help.

“We have the room and they don't," said Robert Traister. "They have so many people down there and when it gets into the 20s and 30s, it's rough out there.”

And Carla Traister adds homelessness doesn't recognize county boundaries.

“When you're talking about where they reside, they don't have a residence so they're not really of this county or from this county or from their county, they have no home,” she said.

But they will have a place for at least two nights. The shelter is already mobilizing volunteers for a second night Wednesday.

Those who stay at the shelter are given dinner, breakfast and fresh clothing.
