A powerful winter storm has recently swept across multiple states in the U.S. Midwest and East, bringing heavy snow, ice, and extreme cold that have paralyzed transportation, caused power outages, and severely disrupted daily life. In response, at least ten states—including New York, Pennsylvania, Ohio, and Michigan—have declared states of emergency. Authorities have mobilized emergency response teams, opened warming centers, and urged residents to avoid non-essential travel.The National Weather Service forecasts snowfall exceeding 30 centimeters (about 12 inches) in some areas, with wind chill pushing perceived temperatures below -20°C (-4°F). The hazardous conditions have already led to numerous traffic accidents, widespread flight cancellations, and temporary closures of schools and businesses. Surging energy demand has also strained the power grid, resulting in rolling blackouts in certain regions.Experts attribute the storm to a southward dip of the polar vortex, consistent with the increasing frequency of extreme weather events linked to climate change. The Federal Emergency Management Agency (FEMA) is coordinating with state governments to ensure adequate supplies and personnel are available. The public is advised to closely monitor weather alerts, stock up on essential supplies, and check home heating systems for safety to weather this cold wave safely.
近日，一场强冬季风暴席卷美国中西部和东部多个州，带来大雪、冰冻和极寒天气，导致交通瘫痪、电力中断，并对居民生活造成严重影响。为应对极端天气，包括纽约州、宾夕法尼亚州、俄亥俄州和密歇根州在内的至少10个州已宣布进入紧急状态。政府紧急部署救援力量，开放避寒中心，并呼吁民众避免非必要出行。气象部门预测，部分地区降雪量可能超过30厘米，风寒效应使体感温度降至零下20摄氏度以下。恶劣天气已造成多起交通事故，部分航班取消，学校和企业临时关闭。能源需求激增也给电网带来压力，部分地区出现轮流停电。专家指出，此次风暴是受极地涡旋南下影响，与气候变化背景下极端天气事件频发的趋势一致。联邦应急管理署（FEMA）正与各州协调资源，确保应急物资和人员到位。公众被提醒密切关注天气预警，储备必要物资，并检查家中供暖设备安全，以平安度过此次寒潮。
