7.2"  on my station gauge.  Will check cocorahs one in the morning.

Did anyone hear about the levee breaking in bound brook?

Bound Brook and Manville must be wiped off the map...

I've never seen our town this bad

Just got a Tornado warning on my iPhone at work in Smithtown

RGEM did very well. Quite a few of its runs had a swath of 8 to 10 inch rains going across central NJ.

[winterwarlock]

8.18 inches here..starting to wind down

[Rjay]

There was likely a spin-up west of Lloyd Harbor

Walt - any thoughts on river flooding levels for the Raritan and other major rivers?  Floyd type levels or less.  Seems like there was a bit more rain in Floyd (10-14" common in the Raritan watershed vs. 7-10" now, by my quick inspection), but antecedent conditions before Floyd were much drier, so maybe it'll be close.  

Latest Raritan flooding forecast is several feet less than it was for Floyd, which had record flooding on the Raritan. Will still be major flooding, though according to the graphic, assuming that graphic is correct.

I think NJwx85 makes the best point; the Passaic will back the tributary rivers up; exacerbating the problem. 

That river meets the Whippany and Rockaway rivers before the Pompton. It’s a tremendous volume of water that drains a large part of northern NJ. And that’s just the Passaic. The Raritan river watershed will be worse in my opinion based on the numbers so far. Downtown Bound Brook is going to be annihilated.

But look at the current obs, compared to forecast. The trajectory could easily rival Floyd. I don’t wish that on anyone.

Floyd always gets downplayed for some reason.....granted it happened at the tail end of a major drought

Crazy shit coming off the ocean now

Historic flooding in SEPA, still pouring there:

Indeed, runoff usually lasts 24 hours after rain stops so rivers won’t crest until tomorrow night.

That was a legit storm. The main road in my town was flooded and we didn’t have school for two or three days.
