Texas death toll from February storm, outages surpasses 100

The majority of the deaths are associated with hypothermia, according to the Texas Department of State Health Services on Thursday. The number could continue to rise as officials link more deaths to the storm that knocked out power to more than 4 million customers in Texas. 

Many homes went without power or drinkable water for days after subfreezing temperatures, failing power plants and record demand for heat pushed Texas'' electric grid to the breaking point. 

Texas officials earlier this month put the initial tally of deaths at 57 but warned it would increase. 

The disaster has launched a congressional investigation and led to the ouster of the head of the state's embattled electric grid, the Electric Reliability Council of Texas.
