As rain and cold mixed Thursday night, the city of Austin says 423 people chose to utilize the city's overnight cold weather shelters.

The shelter, at 3230 Brick Church Pike, will open at 4 p.m. and close at 10 a.m. on Friday, Saturday and Sunday.

The City of Houston is directing people to overflow shelters as temperatures plummet into the thirties amid rainfall, creating potentially life-threatening conditions for the homeless population. Local officials warn that the combination of cold and wet weather poses a severe risk of hypothermia for those exposed to the elements.
