The United States is bracing for one of the most severe weather events of the season, as a powerful winter storm, dubbed "Vern," is expected to batter large swaths of the country. The storm is accompanied by record-breakingly low temperatures, putting authorities and citizens on high alert for potentially catastrophic damage to infrastructure and transportation.
Storm range and its direct impact
According to the National Weather Service, Tropical Storm Fern will be a massive storm, covering an area of approximately 3,219 kilometers (2,000 miles), or more than half the length of the United States. This deep low-pressure system is expected to sweep across a vast region stretching from Texas and the Great Plains to the Mid-Atlantic and Northeastern states. It is estimated that more than 175 million people face the risk of power outages and frozen water systems, as well as widespread disruption to air and land travel.
State of emergency declared in Texas amid renewed concerns
With the storm expected to peak on Thursday and Friday, Texas has declared a state of emergency. This proactive measure comes amid genuine concerns about a repeat of past scenarios where the state suffered power grid failures during freezing temperatures. Texas is a climate-sensitive region for such storms, as its infrastructure is not always equipped to handle extremely low temperatures, making these warnings crucial for protecting lives and property.
Weather forecast details and warnings of "deadly danger"
Meteorologists warned that the impact of the polar air mass would be severe, particularly on Virginia and Maryland, which could bear the brunt, with snowfall expected to exceed 30 centimeters. The National Weather Service explained that freezing temperatures would blanket the eastern two-thirds of the country behind a cold front moving directly from the Arctic.
Perceived temperatures are expected to drop to dangerously low levels, as low as -46 degrees Celsius in the northern plains, accompanied by strong winds that will increase the feeling of cold and create life-threatening conditions, such as frostbite within minutes of exposure to the open air.
Climate context and economic impacts
This storm is part of a polar vortex phenomenon, which allows extremely cold air to escape from the Arctic and travel south. Historically, these storms cause billions of dollars in economic losses due to the cancellation of thousands of flights, disruptions to supply chains, and increased strain on energy grids for heating. The effects of this cold front are expected to extend to the Middle Mississippi Valley and the Ohio Valley by Sunday, prompting residents in those areas to take all necessary precautions and stock up on supplies to weather these challenging days.
