Glossary: Weather Bomb
Weather Bomb
Weather bombs are the most severe of all winter storms. They are characterized as intense low-pressure systems with a central pressure that falls 24 millibars or more in a 24-hour period.
When a low-pressure system develops over the Atlantic, just off the Carolina coast, it gathers moisture from relatively warm ocean water. If the jet stream is far enough south it brings cold air that combines with the warmer air from the Gulf Stream. A Weather bomb is then created.
Weather bombs are known for dumping heavy amounts of rain and snow, producing hurricane-force winds, and creating high surfs that cause severe beach erosion and coastal flooding.
