Thanks Paul and I didn't even get hit hard.
I just spoke with Vinman. He's doing OK, exhausted, tired, and being a hero. His home and family is OK.
His crew rescued a rescue crew from an area. The stuff real hero's are made of. He's been deployed since Sunday night & still working.
And to Johnco... I know you didn't mean any harm with your comments but there is more to a storm than a number that the government lends to it. There are extenuating circumstances like timing, moon phases, high tide, rotation, etc. etc. that go into a storm.
John Tepper Marlin: Hurricane Sandy's Severity - #5, #6 or #8
A snippet...
2. Millibars -- Barometric Pressure. The Christian Science Monitor has posted a lucid summary of the significance of this measure of hurricane severity. (It also repeats the error cited above about the cost of Hurricane Irene -- I will return to this.) Ordinarily, the barometric pressure is related to wind speed. The normal sea-level barometric pressure is 1013.5. During a hurricane the eye of the storm shows the lowest barometric pressure. The lower the pressure, the higher the winds. During the afternoon before Sandy hit landfall,the barometric pressure at its eye fell from 943 to 940, which is a level associated with Category 3 or Category 4 winds. The lowest barometric pressure that has been measured in a U.S. hurricane is 882 for Hurricane Wilma. Hurricane Carla was the tenth-lowest, 931. The National Hurricane Center list of the most intense Atlantic hurricanes does not follow the Millibars ranking exactly, since Katrina and Wilma are not in the order one would expect. Irene is not among these most intense hurricanes. So the prospective readings are not a definitive measure of impact.
3. Storm Surge Impact. Most of the damage from Hurricane Sandy is caused by the delayed impact of the storm surge (the hurricane equivalent of a post-earthquake tsunami). We needa new indicator of likely flood damage, which would have to take into account the economic value of property in the track of the hurricane, the sea level of the land, and the size of the expected surge. The Storm Surge Impact index could take into account the timing of the tides -- Hurricane Sandy hit landfall near high tide and the full moon added to the height of the tide and therefore to the surge. The geography of the surge was important in the case ofNew York City because the surge came from two directions -- down the Connecticut coastline through the Long Island Sound and northward through the funnel of New York Harbor.
