US Braces for Treacherous Winter Conditions as Freezing Fog and Snow Blanket the Country

A severe winter storm is gripping large parts of the United States, making driving hazardous and disrupting daily life. Freezing fog, a phenomenon where fog droplets freeze instantly on contact with surfaces below 32°F, has been reported in several cities, including Maryland, North Carolina, Washington, D.C., and Virginia. According to the National Weather Service (NWS), freezing fog can lead to the formation of black ice on roadways, making them slippery and increasing the risk of accidents. The NWS also warned of reduced visibility, with some areas experiencing conditions as poor as one-quarter mile or less. The NWS issued advisories for 18 million people in six states, including Alaska, Colorado, Illinois, Iowa, Wisconsin, and Wyoming, where heavy snowfall is expected. In addition, around 4,000 flights have been delayed, and 550 flights have been cancelled. The cold snap is expected to persist, with multiple clipper systems moving through the country and bringing low temperatures. The Northern Plains and Upper Midwest will experience a steady stream of snowfall, while the Great Lakes region may see another clipper system bringing more snow. Residents can expect no respite from the cold weather in the coming days, with forecasters predicting continued harsh conditions. The flood threat in states like Washington and Oregon adds to the woes of the winter season. FAQs: What is freezing fog?
