Update From the Weather Nerd


  ” If my reading of the Battery Park tidal gauges (charts here and here ; raw data here ) is correct … and if my understanding is right that a water level ( i.e. , the red line
on the charts) higher than 10 to 10.5 feet would cause a major flooding event in New York City that would inundate the subways
and swamp low-lying areas of the city … it appears to me that, unless the storm surge ( i.e. , the green line on the charts) slows down from its current pace of increasing
approximately 1 foot per hour, a
significant New York City flooding event will begin sometime in the 5:00 to 6:00 PM hour local time, probably closer to 5:30 or 5:40 PM, but in any event well before the 9:00 PM high tide (and thus,
presumably, continuing unabated for several hours). “



  ” The projected storm surge from
Hurricane Sandy is a “worst case
scenario” with devastating waves and tides predicted for the highly
populated New York City metro area, government forecasters said Sunday. The more they observe it, the more the experts worry about the water -which usually kills and does moredamage than winds in hurricanes.

  In this case, seas will be amped up
by giant waves and full-moon-
powered high tides. That will
combine with drenching rains,
triggering inland flooding as the
hurricane merges with a winter
storm system that will worsen it and
hold it in place for days. “
