Icy roads, power outages and dangerously low temperatures have been making life miserable in many states, including some that are unaccustomed to such harsh winter weather.
In Texas, for example, people have been struggling for heat and water. State officials say the deep freeze that started Sunday crippled utilities' power generation, causing rolling blackouts or continuous outages.
Since February 11, at least 38 people have died nationwide from winter storms or frigid conditions.
