A significant snowstorm has engulfed the Northeastern United States, forcing millions to stay indoors due to blizzard warnings and widespread travel disruptions. The National Weather Service has classified the event as a 'classic bomb cyclone/nor'easter,' emphasizing its rapid pressure decrease and intensifying weather conditions. The storm has brought strong winds and heavy snow, leading to near-zero visibility in many areas and causing over 500,000 customers to experience power outages. Utility companies are actively working to restore power, but progress is hampered by the continuing storm and hazardous conditions.
