A powerful coastal storm will unleash soaking rain and howling winds through Thursday from the Mid-Atlantic to New England.
The strong winds – potentially gusting up to 60 mph – may cause some tree damage and power outages, the National Weather Service said. Up to 3 inches of rain could fall in this storm, especially from eastern New York to southern Maine, where flash flooding is possible.
The latest forecast shows the storm will strengthen at a fast enough pace from Wednesday to Thursday to be classified as a “bomb cyclone,” AccuWeather said. The barometric pressure has to fall at least 24 millibars, or 0.71 inches, in 24 hours for the bomb cyclone criteria to be met, in a process known as bombogenesis.
The lower a storm’s barometric pressure, the more intense the storm. Weather Channel meteorologist Greg Diamond said some record low barometric pressures for October could be set.
CNN meteorologist Dave Hennen said, “The system will have the equivalent low pressure of a Category 1 hurricane.”
