Dallas (AP) – Higher temperatures are spreading across the southern United States, bringing some relief to a region now very weary of winter. The region faces a challenging clean-up and expensive repairs from days of extreme cold and widespread power outages. In hard-hit Texas, where millions were warned to boil tap water before drinking it, the warm-up is expected to last for several days. President Joe Biden has declared a major disaster in Texas, directing federal agencies to help in the recovery. More than 70 deaths are being blamed on the weather, nationwide.
