In Pictures: Subfreezing cold sweeps through Texas

Officials say a frigid blast of winter weather across the United States is likely to blame for the deaths of two people in Texas as temperatures dropped into the single digits Fahrenheit, (-22C) and snow shut down air travel and grocery stores. More than four million people were without power Monday evening after surging demand was driven by people trying to keep their homes warm, and cold weather knocked some power stations offline and pushed Texas’s system beyond its limits. After a facility storing 8,000 doses of the Moderna vaccine in Houston lost power, health officials hurriedly worked to distribute it before it expired at the same time authorities were pleading for people to stay home.
