Texas officials have added 59 deaths to the toll wrought by a February cold spell and the ensuing collapse of the state electric power grid.
The deaths newly tallied by the Texas health department lifted the toll from 151 aan 210, most from exposure to sometimes-subzero temperatures. Some deaths were blamed on carbon monoxide poisoning as freezing Texans sought warmth from cars and outdoor grills.
The count remains preliminary and may change as more deaths are confirmed, the department said.
The county with the highest death toll was Harris, where Houston is situated, met 43 sterftes. Travis county, where Austin holds most of its population, had 28 sterftes. Dallas county reported 20 sterftes.
An initial 15 March report put the toll at 57 sterftes. The toll was raised to 111 aan 25 Maart, 125 aan 6 April and 151 aan 28 April.
The collapse of the power grid managed by the Electric Reliability Council of Texas (Ercot) has made electric reliability in Texas, a Republican-run state, a key political question.
In early June, Governor Gregg Abbott declared that state lawmakers had fixed the problem during its regular session that had just adjourned.
Since then, two conservation alerts issued by Ercot during temperate weather prompted renewed questions. Abbott ordered new measures from a public utility commission he appointed and which oversees Ercot.
