OBS for moderate coastal impact Nor'easter Sun-Mon 10/12-13/25 with needed rain everywhere. To minimize any disruptions review NWS warnings-statements.

Visuals with power problems, even in nw NJ at 620AM Rides running 3' a move normal right now so a very good chance of moderate coastal flooding with the midday-afternoon high tide.

Winds a little lower than expected on LI but the Fire MIN GUST tool from SPC HREF set the bottom line very well.

So... here are some visuals on rainfall, power outages and airport gusts 46MPH or greater the past 3 hours ending around 6AM.

Added the most likely scenario for the afternoon high tide, SANDY HOOK representing the onshore packed in water.  Rainfall runoff and backed up streams that empty into the Atlantic will exacerbate the flooding this afternoon. So far, no official storm reports that I can see from OKX.

Very moderate event as the system split into two weaker lows instead of one strong consolidated one. Generally 1 to 1.5 so far for my area. While we have had much heavier rains with October nor’easters in the past, I will take it since we need the rains.

Isolated spots may be pick up an additional 2" between now and 8PM, along the coasts... IF convection emerges this afternoon as modeled by the HRRR.

Looks like pretty good impact,  travel wise per TV reports and what has been posted here this morning. Anticipate DELAYS and maybe some detours. 

Will post a summary report tomorrow morning around 9A, for CoCoRaHs 3 day totals but looking good.  Wind driven rains this morning... intermittent in some spots.

Officially past 2 inches for the entire event Sat-now at Holmdell NJ, Queens and Stony Brook on LI.  Suggests to me that iso 4 within the realm of possibility. Otherwise bigger amounts of at least 4" will probably be coastal RI out to Cape Cod. 

Sharp cutoffs continue to be a feature.  This will be fun this winter.  I'm up to 0.30" event total from 0.21" overnight.  Wind is howling this morning.  I didn't witness any power outages as of yet in my travels out this way.
