A 39 year old man from East Flatbush, Brooklyn died this evening due to the flooding. He drowned while saving his dog.

[Picard]

Currently moderate rain, probably winding down - I got a nice burst from that line which brings my event total to 1.33".

[Nibor]

My apartment flooded. So lucky I was home and able to deal with it. 

[wthrmn654]

Rain stops and winds are increasing...

[MANDA]

Tragic.

Just heartbreaking.

2.23” total

2.44” all said and done.

Still raining moderately here.  Up to 2.57" on my automated gage, but it usually runs slightly high.  I'll trust the 4" gage when I check it in the morning.  We had just about an inch after the remnants of the initial heavy batch that flooded Brooklyn passed through, but have been making up for lost time since

The last round of rain brought me to 2.9. It's still drizzling.

Finished with only 0.98" here in Lindenhurst.

Ended with 2.48"

Currently 46.6°

I'll have a wrap up post around 930A inclusive of two day CoCoRaHs and one or two other graphics regarding predictability (the 1+"/ 30 min rainfall was not predictable in my opinion except short fuse warning).

The shaft zone was roughly the Suffolk border to about 8 miles or so east. I have maybe 1.4” here. Better than it could have been.

None of those storm drains in Brooklyn where the worst flooding occurred were built to handle 1.00” of rain in only 15 minutes. While the spots that got over 2” yesterday wasn’t their heaviest daily rainfall event in recent years, 1 inch of rain in 15 minutes is probably close to the all-time records for the individual spots in an around Crown Heights.

We did get some minor tidal flooding along the roads bordering the Great South Bay, Went to Babylon dock and the water was maybe a few inches above the docks themselves at high tide. Seeing the boats at a higher level than you are is always a weird sight regardless of how bad the flooding is

1.85 here for rainfall
