Looks like the actual tide level is a little lower than the Tax Day nor'easter in April 2007 and close to 10/18/2009. I think it might have been higher then both of those here. I'm trying to figure out which storm it was on par with. Irene was definitely about a foot higher. And despite the weaker winds it was higher then march 2010.

Looks like Orange county was the sleet jackpot as pretty much called by the NAM 2 days ago. All hail the NAM. You mean all sleet the nam ;-) I guess cutting the nam totals a bit worked well too.

Actuallly the NAM pretty much nailed it. Both with precip and temps Sleet is 3:1 so if this was snow it would have been 10-12". Pretty much what those silly snow maps were printing out for the area. And it did change to snow at the end Link to comment Share on other sites More sharing options...

So if it was all snow it would've been around 25" of snow- which is what I saw on some of the more robust NAM maps. I think those maps use 2:1 for sleet so 10:1/2:1 =5 times 5"=25".

I flipped to decent snow by 330 am and it came down pretty heavy for about an hour before turning back to light sleet around 6... if I had to guess I'd say up here 3" of sleet and close to 2" of snow Link to comment Share on other sites More sharing options...

It sounds like the higher rates by you meant more sleet and snow rather than the freezing rain that areas further NW and higher up got, because they were on the edges of the storm and didn't see the rates you did.

I think it was actually low level cold and lower elevation as oppose to actual Latitude, seems the closer you were (higher elevation) to that warm nose... the less time for re-freeze, resulting in a more liquid sleet/freezing rain combo... being in the valley here yet far enough north and only around 380' elevation helped big time. Albany mentioned in their advisorys that higher elevations would see freezing rain as oppose to valleys... not often you see that Link to comment Share on other sites More sharing options...

jm1220 Posted January 24, 2017 Share Posted January 24, 2017 The water came up pretty high this morning. There was definitely flooding in the low lying spots around Long Beach and other towns around here. Driving into Queens this morning was a nightmare.

Oh yea...
