Cities across Texas are preparing for widespread outages in cell phone and water services as the state continues to be pounded by a ferocious winter storm, which has already left millions without electricity. Ravaged by the first storm on Sunday night, Texas’ power grid has taken a beating over the last 24 hours, leading to rolling blackouts across the state for around 4.3 million residents as officials rush to repair ailing infrastructure. The power outages have set off a cascade of other problems, knocking some water treatment plants and cell phone networks offline.
