Almost two weeks after Beryl hit, heat-related deaths during the prolonged power outages have pushed the number of storm-related fatalities to at least 23 in Texas.

The combination of searing summer heat and residents unable to power up air conditioning in the days after the Category 1 storm made landfall on July 8 resulted in increasingly dangerous conditions for some in America’s fourth-largest city.

Beryl knocked out electricity to nearly 3 million homes and businesses at the height of the outages, which lasted days or much longer, and hospitals reported a spike in heat-related illnesses.

Power finally was restored to most by last week, after over a week of widespread outages. The slow pace in the Houston area put the region’s electric provider, CenterPoint Energy, under mounting scrutiny over whether it was sufficiently prepared.
