Heat-related deaths in Texas climb after Beryl left millions without power

Deaths during prolonged power outages pushes number of storm-related fatalities to at least 23 in Texas

As the temperature soared in the Houston-area home Janet Jarrett shared with her sister after losing electricity in Hurricane Beryl, she did everything she could to keep her 64-year-old sibling cool.

But on their fourth day without power, she awoke to hear Pamela Jarrett, who used a wheelchair and relied on a feeding tube, gasping for breath. Paramedics were called - but she was pronounced dead at the hospital, with the medical examiner saying her death was caused by the heat.
