At least 111 Texans died as a result of last month's winter storm, according to updated numbers released Thursday by the state Department of State Health Services.
The newly revised number is nearly twice what the department had estimated last week, and will likely continue to grow. Some of Texas' larger counties, such as Tarrant County, have yet to report any storm-related deaths.
The majority of people died from hypothermia, but health officials also attributed deaths to motor vehicle wrecks, "carbon monoxide poisoning, medical equipment failure, exacerbation of chronic illness, lack of home oxygen, falls and fire."
Among those who lost their lives in the frigid weather was an 11-year-old boy in the Houston area who died in his home as temperatures dropped into the single digits. In San Antonio, a man froze to death outside his house after he likely fell on his way to a dialysis appointment. And in Abilene, a man reportedly froze to death in his reclining chair.
Harris County reported 31 storm-related deaths, the largest share in the state. Travis County followed with nine deaths.
Health officials will continue to update their preliminary findings weekly.
According to DSHS, the data is compiled from forms that certify deaths are related to a disaster, notification from death certifiers and analyses of death certificates from state epidemiologists.
February's winter storm blanketed large swaths of Texas in snow and ice and left millions without power or clean water for days in below-freezing temperatures.
The issues laid bare by the freeze have taken center stage at the Texas Legislature. A Texas Senate committee on Thursday advanced a wide-ranging bill that would, among other things, mandate that power and natural gas companies upgrade their facilities to withstand severe weather. It would also create a statewide emergency alert system for future large-scale power outages.
Meanwhile, executives at billionaire Warren Buffett's Berkshire Hathaway Energy have been lobbying Texas lawmakers to support an $8 billion plan to build 10 new natural gas power plants that would provide energy during peak consumption hours when demand is highest. The company wants lawmakers to create a revenue stream to Berkshire through an additional charge on Texans' power bills.
