I dunno why you say that as if the eye is making landfall right now, its still roughly 100+ miles out to sea and still has somewhat of a NNW heading, theres still at least 4-5 more hours for it to continue drifting and the eye can still totally clip the eastern part of the Island. Either way its pretty much irrelevant whether the eye barely misses the island by a mile completely or whether it landfalls 10 miles into the east end, the outcome and impact for a majority of the island will be nearly the exact same. Henri is still going to cause widespread, significant problems for the area. How far west it drifted had much more of an impact on the CT/Mass/RI area than it did LI.

You are wishcasting.

Unless the storm puts on a turn signal and makes a sharp left turn, The eye is not landing on Long Island.

 

Of course there are widespread effects outside of the eye.

 

But the thinking of a landfall between Smith Point Park and Southampton was off by 100 miles…I am glad to say

So we will by 2PM know how we stand on wind and power outages, initially.  Then dealing with pockets of 30-40 kt gusts during the night, high terrain NNJ/se NYS with weakened root systems could add to the total power outages.  

My concern, as many, is the additional 2 to possibly 12" of rain in our subforum by late Monday night. My focus continues NNJ/ne PA/Catskill region where I think we pound tonight and Monday morning with widespread 3-7" isolated 10".  If this occurs as I anticipate,  has to result to in moderate or greater stream flooding, some small fast responding streams with bridge washouts/road closures ne PA, NNJ, se NYS.  

I've added previous week rain departure which to me focuses, most favorable flood area ne PA, nNJ.  Also some FGEN guidance that I like which is verifying nicely. See 11z radar today and the expected shift north with interim guidance not shown.

NYC just set its new heaviest hourly rainfall total at 1.94”. The 8th heaviest hourly total was set back in July. Notice how many hourly records were set in recent years.

[Snowlover11]

rain has moved back in, lets flood.

[eyewall]

Landfall should be somewhere in southwestern RI. This means not much of a wind event for central/western LI and NYC. Some low end TS winds in gusts for the most part, especially east. This is a rain event for the NYC Metro mainly.

A bunch of hobbyists at home once again make corporate funded meteorologists and news outlets look like complete idiots. Nice job everyone.

How can models be so wrong already esp a short term hrrrrrr

Lucked out here with the wind  Very heavy rain right now with very little wind 

[nycsnow]

Complete model failure with the rainfall half of them don’t even have nyc getting this rain today let alone what happened last night 

[lee59]

After 1.5 inches of rain last night, I have received .17 from Henri. Light rain falling, very light winds.

[Tatamy]

Following two WU stations on BID as the NW eyewall of Henri approaches.  Highest gusts so far are 54 and 56 mph.

All the LI Airports last hour.

 

Gusty from Brookhaven out.

Even Islip is fairly calm

The rain band that impacted NYC and NJ last night sort of reached way out from the storm.

It seemed unusual, but it is still surprising that the models did not recognize the precipitation potential. Wonder what lessons will be learned from this.

The best part is the TAFs...60kts at ISP and 44kts at JFK.  My hunch is there is some sort of agreement to appease NHC for the warnings because 925 winds do not support anything remotely near that.

You have to go out to eastern Suffolk to find strong winds.  I found a station out in Baiting Hollow at Reeves Beach on WU overlooking the Sound with a recent gust to 49 mph.

Yeah I would say til 21Z there could be solid rains NYC east and even NRN NJ.  I think though that most places won't exactly see tons of rain based on radar though...some pockets will pull off 3-4-5 inches though

WXunderground.  52-56 MPH on BID.  will add graphic soon.  Also 44017 s of MTK gusts 43 kt and increasing.  Mesonet gusts e LI are getting into the mid 30s now.
