A powerful winter storm has swept across the Northeast, dropping heavy snow that has disrupted air travel and created hazardous road conditions. Parts of the Tri-State area received as much as 8 inches of snow, leading to significant delays at major airports including JFK and PHL, where ground stops were implemented. The National Weather Service issued multiple winter storm warnings, predicting up to 24 inches of snow in some regions and advising residents to stay indoors due to life-threatening conditions. Travel chaos was reported nationwide, with over 1,000 flights delayed during the holiday season. Meanwhile, the Pacific Northwest is bracing for an influx of rain as winter weather alerts affect approximately 18 million people across the country.
