Millions of Americans from the Great Lakes to the Northeast are under the threat of a bomb cyclone as a powerful winter storm sweeps across the region. Meteorologists issued alerts on Monday, warning that snowfall totals in parts of the Great Lakes, New York, New Hampshire and Maine could reach up to two feet in the hardest-hit areas. A bomb cyclone, also known as bombogenesis, is a rapidly intensifying low-pressure system capable of producing extreme and dangerous weather. #news #weather #bombcyclone #snow
