A powerful and far-reaching winter storm is accelerating eastward, placing nearly two-thirds of the United States under escalating weather threats. Forecast models indicate a rapidly intensifying system stretching from Texas to New England, capable of delivering crippling ice, heavy snowfall and extreme Arctic cold over several days. A critical 72-hour window highlights a direct hit along the I-95 corridor, with cities from Washington D.C. to New York and Boston facing the potential for disruptive snow and damaging ice. Forecasters warn that ice accumulation in some regions could rival hurricane-level impacts, particularly where power infrastructure is most vulnerable. WATCH
