The powerful winds blowing through Houston not only brought a frigid feel to the city, they bring high demands on power. 

ERCOT, the council that manages the Texas power grid, has put out a warning, asking energy customers to conserve power in order to avoid power outages. No problems have been reported yet.

Low temperatures also drove many people to open their hearts to the less fortunate.

All afternoon long, volunteers at The Star Of Hope Mission hit the streets to hand out warm coats, blankets, hats and gloves to dozens of homeless men and women on Sunday.

People like 26-year-old Justin, a culinary student at one time who is now living on the street with his two dogs, received items to help him stay warm.

"It's a blessing, and it's there way of spreading the love of God.  I am so glad that they are giving us blankets and stuff to keep us warm," said Justin.

Across town at one of the many Home Depot stores, homeowners stood in line to buy foam insulation for their pipes. The weather forecast calls for a hard freeze, and at 19 degrees, experts say homes in Texas can be at risk for damaged pipes that can burst if they become too cold.

Hard freeze temperatures are expected to stick around another day as the polar vortex blows through the midwest.
