HOUSTON (AP) — Hospitals across the South are grappling with water shortages as the region carries on with recovery efforts in the wake of a devastating winter storm. Meanwhile, the weather offered a balmy respite — temperatures as high as the mid-60s in Houston. At the height of the storm, hospitals were left scrambling to care for patients amid record cold, snow and ice. The storm was especially damaging in parts of the country more accustomed to going through winter with light jackets and short sleeves. The icy blast ruptured water mains, knocked out power to millions of utility customers and contributed to at least 76 deaths.
