It's unbelievable that this happened just a week and a half after our area was devastated by that incredibly severe t-storm that had 70 to 80mph winds. 

It really is. Like besides Ida and sandy these are the 2 most significant weather events since I've lived here, 10 days apart

Looks like 3.5" will do it, and that's on the low side.  Some nearby stations are over 4 inches, closer to 4.5" actually.

Had some bouts of incredibly torrential rain.  Literally went from needing to add water to the pool, to having it filled to the brim and needing to drain it.

Guess all of our insurance premiums will be increasing faster next year.

The most important thing is people walking away safely, which hopefully everyone did tonight.
After that, then looking at the property losses, including vehicles.  The costs and resources to repair or replace these things is astronomical these days, and with modern day cars, it doesn't take much water incursion to completely ruin it or run a tab into the tens of thousands in repairs.

Yesterday, White Plains picked up 3.38" of rain. That smashed the daily record of 1.63" from 2014. That was also the second highest amount for any day in July. The highest amount for any day in July was 3.44" from July 18, 2022. It was also White Plains' 7th highest summer (June-August) daily rainfall on record. It was White Plains' biggest rainfall since September 29, 2023 when 4.10" fell.

New York City (Central Park), Newark, and White Plains all received 2.00" or more daily rainfall for the first time since March 23, 2024. The last time all three stations saw 2" or more daily rainfall during the summer was August 22, 2021.

NOTE: The PNS shows 2.95" at White Plains. The climate record in XmAcis shows 3.38".

0.82 here i9n this part of Wantage NJ.  I'll be looking for a listing of NWS posted rainfall amounts from OKX and PHI on this thread later today.  Can't do CoCoRaHs post till this afternoon. 

am looking at probably one more FF/SVR thread this week centered on Sunday into early Monday.  Small chc thread for Wed afternoon-Thu but am pretty sure we'll need a thread for Sunday, in part due to antecedent pockets of saturated turf.

Thanks for this Don--- hoping they update this better reality by Noon today.  Clearly more than 5" fell. Response is pretty severe in parts of NYC subforum.

At least 3 reports of 6”+ from Union County where the SPC HREF had its local max. So a good performance from the model. This almost had some PRE-like characteristics with the weak tropical low near Florida.

South shore getting a nice batch of rain currently adding to the .5” from yesterday. I’ll take it. 

By the way whomever said Long Island wouldn't get much rain was wrong, we had heavy rain last night and it was still raining here pretty hard around 8 AM this morning, it only ended just before 9 AM here, we had over 12 hours of rain!!

We got over an inch of rain here

Looks like about 0.75" to end it.

I dont understand why people thought the cooler ocean would weaken it, it rained for over 12 hours here and we had well over an inch on the south shore.  The oceans are much warmer now, the ocean won't be weakening anything anymore, if anything it adds more moisture to make the rain heavier.
