February’s disastrous and deadly winter storm impacted most Texans served by the state’s main power grid, with almost 70% of those people losing power in subfreezing temperatures and almost half experiencing a water outage, according to a new report from the University of Houston. And although Texans were told to prepare for short-term, rolling power outages ahead of the storm, those who lost electricity ended up going an average of 42 hours without it, the survey found. As the updated death toll from the storm reached 111 deaths last week, the severity of its full force has continued to come into focus. The damage the storm wreaked could make it the costliest disaster in Texas history.
