Coastal Storm Brings Damaging Winds
A powerful coastal storm with very strong winds and heavy rainfall is undergoing bombogenesis near the East Coast, resulting in tree damage, power outages and flooding.
Rapid intensification of the low pressure system is ongoing near New York City, and it is expected to continue to rapidly intensify as it moves into the Hudson Valley overnight.
Bombogenesis is a rapid deepening of pressures in a storm, which rapidly increases winds near the center of the storm. Scientifically, bombogenesis is defined as a drop of 24 millibars in 24 hours.
So far, winds are gusting in the 30-50 mph range so far near the coasts of New Jersey, Maryland, Long Island and Massachusetts. Winds as high as 70 mph have been reported in the higher elevations of New England. These winds may increase through the late evening into the morning hours.
One of the ingredients for this coastal storm is a powerful jet stream disturbance sweeping through the eastern states that will help induce the formation of a strong low-pressure system near or off the mid-Atlantic and Northeast coastline. This storm system is receiving an injection of moisture and energy from ex-Tropical Storm Philippe, currently tracking quickly northward to the east of this parent low pressure system, as well as the cold front sliding through the East Coast.
