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). “
