Re: "SUPER STORM" for the northeast?
Glad you guys did ok. Just imagine what a cat3 is like.
This was just as bad because of the unusually high barometric pressure
Yet, the superstorm's climbing barometric pressure is more typical of category 3 or category 4 storms, making it likely that Hurricane Sandy will rank relatively high on the list of the most intense hurricanes to hit the U.S. since 1851.
According to a recent bulletin from NOAA's National Hurricane Center, Hurricane Sandy's minimum central pressure is hovering around 940 millibars. Comparatively, Hurricane Katrina, which hit Louisiana and Mississippi in 2005, was classified as a category 3 hurricane with a barometric pressure of 920 millibars -- making it slightly more intense than Hurricane Sandy's present levels.
