Houston, which doesn't typically experience cold weather, has the most stringent guidelines for opening warming centers compared to other Texas cities.

The city only opens warming centers when temperatures dip to 24 degrees for at least two hours. Instead, the Mayor’s Office of Public Safety and Homeland has been coordinating with private facilities.

As frigid temperatures descend upon Houston, city officials and residents are taking precautions to protect themselves from the cold, including potential power outages and hypothermia.
