A powerful winter storm system is expected to develop along the south-eastern coast of the United States in the coming days, potentially evolving into a “bomb cyclone”, according to meteorological forecasts. The system could bring heavy snowfall, gale-force winds and dangerously low temperatures to large parts of the eastern US.
The new storm comes as many regions are still recovering from a major winter system that affected the country last weekend, dumping more than 50 cm (20 inches) of snow in some areas, disrupting air travel, cutting power to hundreds of thousands of homes and contributing to multiple fatalities.
Another winter storm on the way
Forecasters say the new system is expected to develop near the Gulf Coast on Friday, pushing a mix of rain and snow across the Ohio and Tennessee Valleys. By Saturday, the storm is forecast to rapidly intensify as it moves into the Atlantic Ocean, potentially turning into a nor’easter — a powerful low-pressure system known for producing heavy snow, strong winds and coastal impacts along the US East Coast.
The Mid-Atlantic region is expected to be among the hardest hit areas, with snowfall totals possibly reaching up to 15 inches (38 cm) in some locations. Winter storm watches have already been issued for parts of Georgia, South Carolina, eastern Tennessee, North Carolina and southern Virginia.
Strong winds, coastal flooding and power outages possible
In addition to heavy snow, the storm is expected to bring strong coastal winds and storm surge, particularly along the North Carolina coastline. With high astronomical tides coinciding with powerful onshore winds, coastal flooding and erosion remain a concern.
Meteorologists warn that blizzard-like conditions could develop in some areas, leading to dangerous travel conditions, power outages and further disruption across the region.
Arctic cold tightens its grip
At the same time, bitter Arctic air continues to dominate much of the eastern United States. Temperatures are forecast to remain up to 15°C below seasonal averages, extending as far south as Florida.
Freeze warnings have been issued in parts of the southern US, with overnight temperatures dropping low enough to threaten crops, infrastructure and water supplies. In some areas, snow and ice already on the ground are unlikely to melt, increasing the risk of hazardous conditions if additional snowfall occurs.
Meteorologists note that this could become one of the longest-lasting cold spells in decades for parts of the eastern US.
Why is this happening?
The prolonged cold outbreak is being driven by an unusual configuration of the jet stream, which is allowing Arctic air to plunge far south into the United States. Persistent northerly winds have reinforced the cold, keeping temperatures well below normal and intensifying winter storm activity.
Experts say this pattern is likely to continue for several more days, keeping much of the eastern US under the influence of winter weather well into next week.
