RECORD EVENT REPORT

NATIONAL WEATHER SERVICE NEW YORK NY

949 PM EST MON OCT 29 2012

..RECORD HIGH WATER LEVEL AT THE BATTERY NY

A RECORD HIGH WATER LEVEL OF 13.88 FEET WAS SET AT THE BATTERY NY

TODAY AT 9:24 PM. THIS BREAKS THE OLDEST OFFICIAL RECORD OF 10.02

FEET SET IN 1960 WITH HURRICANE DONNA.

Was the old record at the Battery 10.02 ft or 11.2 ft? I'm seeing conflicting reports. Anyone?

actually, both are accurate. The 10.02 ft is for Donna as the highest recorded height in modern times. The 11.2 ft number is the estimate for the hurricane of 1821, which held the record until last night. So in 300 years of recorded history, Sandy beat the old record of 1821 by 2.7 feet. Sandy might be a 500-1000 year event given standard deviations over a 300 year period of record.

According to neighbors that stayed behind, my house is in bad shape. All houses flooded and ours sits lowest. 7 ft of water came through. I'm itching to get over there. I may have nothing but a couple of bedrooms left on the 2nd floor.

So sorry to hear. Thoughts are with you. :(

Here are the official records from the NOAA Tide and Current site. I have no idea where 1821 comes from. As you can see by the records, there is no 1800 anything there. first, here is the station page for the Battery http://tidesandcurrents.noaa.gov/geo.shtml?location=8518750

The NWS in NYC mentioned 10.02 ft for Donna, so...?

Good question... I haven't figured that out yet.

Donna was 1960 on that September date. It's possible they are talking about surge and not the total water column height. It could be Donna came through at low tide

I'm thinking the higher value is above mean low water or something like that. In my blog post about Sandy and Donna and 1821, I used the 10.02 value: http://icyclone.com/...tober-2012.html

I hear ya Dacula. I'm just relaying what TWC and local NYC media have been saying over the last day. 1821 from my blurb above was an estimate from way back then. I think official readings started in the early 1900's if I recall. The 10.02 number from Josh is what was reported as the record that was officially broken, and the 11.2 number is the record that was unofficallly broken.

Bingo-- and I revised my blog post to reflect that. Thanks for your help: http://icyclone.com/now/2012/oct/30-october-2012.html

16 people killed in AC alone...

Unreal. Sounds like it was people who didn't heed the mandatory evac orders. Just so sad.

Ps, Christie vs AC mayor blame game in full swing right now.

I think the AC mayor is going to come out on the short end of that blame game. Christie was pi$$ed yesterday that his evac order was countermanded by the mayor, who told people to seek shelters. Several citizens confirm the mayor said that, which of course he now denies. I would imagine some lawsuits out of that mess if true.

But you'll notice many values that fall above the 11.2.

I was correcting TWC last night on their Tweets... I'd like to know where they are getting the data, I'd like to see it. You would think NOAA would be correct.

blurb from MSNBC among many other outlets. Doesn't mean their right though:

Seawater surged into lower Manhattan and areas of Brooklyn, submerging entire streets and parks Monday. An all-time record tide level of 13.88 feet was set at The Battery in Lower Manhattan, Monday night, breaking the previous record of 11.2 feet from 1821

Yes... they got the 13.88 correct. I just have no idea where the rest of it comes from. I think a lot of information getting passed around last night was incorrect. Once a person gets it, tweet's it again, 20 people retweet.... and on and on until it becomes "fact".

And I guess my point is that there are 9 records ahead of that 11.2 reading they keep quoting.

At The Battery, the MLLW is about .1 feet (zero for all practical purposes). That's the "normal" level at low tide. They vary on average, 5.06' for great diurnal range or 4.53' mean range of tide. The 13.88 is feet above MLLW. The difference between the 13.88 and the projected tide yesterday is the amount of storm surge.

I'd love to find out where this other data is and who's keeping it!

The 13.30 feet you see here for 12 September 1960 (Hurricane Donna) refers to the water level above station datum (see Datum: StnDatum). But mean lower-low water lies 3.29 feet above station datum. The 10.01 feet (or 10.02 feet) often cited hereon and elsewhere for Hurricane Donna refers to the surge above mean lower-low water. Station datum varies somewhat arbitrarily from station to station, whereas mean lower-low water describes a particular level on the diurnal tidal cycle (the average of the lowest low tide of each diurnal double tidal cycle). Yesterday, the water level at the Battery in New York City reached 13.88 feet above mean lower-low water (or 17.17 feet above station datum).

The storm surge cited for 1821 comes from historical estimates of that storm of unknown accuracy.

Move Jeff L (HCFCD):

Events continue to unfold from record breaking storm event over the NE US.

Governor of NJ: “Damage to the Jersey coast is unprecedented.”

Death toll has risen to 33 up from 16 this morning with damage estimated now at 45 billion dollars!

Severe flooding and rescues continue in the NE part of New Jersey where levees were overtopped by the storm surge inundating three towns.

8.1 million people are now without power and estimated restoration times range from 7 days to over 2 weeks.

80 homes have burned in Queens, New York due to a fire started by arcing power line and then spread from house to house by strong winds.

Helicopter views of the New Jersey coast reveal “incredible damage”. Barrier islands have been cut in half in some places with structures heavy damaged and large 20-25 foot protective dunes completely gone.

50% of Hoboken, NJ has been flooded with sea water.

NJ transit system will be closed until further notice due to damage. Damage to NYC transit system is still not fully known, but it is extensive.

Seaside Heights Boardwalk (Famous from MTV’s Jersey Shore) is gone:

My Mom, up in the W 80s of Manhattan, says things are slowly getting back to normal today.

There are some trees down, and Riverside Park is a mess-- the Hudson had jumped over the banks and onto the pedestrian walks leaving mud and sludge everywhere. And the streets are rather quiet. But they have power-- they never lost it, actually-- and about 2/3 of the businesses are open. Food places like Zabar's are doing brisk business.

Uptown is higher elevation and they clearly did much better than Downtown.

very true...however the upper east side along the east river had some pretty large tree damage to about 2nd avenue. My car was parked on a lot on 97th st and 1st ave and the east river (along FDR) flooded here to almost 4ft. 150 cars , including mine, totaled.

I think the damage to the east side was probably more extensive given the winds. Right along the water the gusts right here had to be over 80mph at times.
