Up to 2.11 inches for the storm so far. Lowest barometer reading was 29.04. Highest wind gust was 27 mph, but my Davis is kind of sheltered from more accurate wind readings.

 

Good afternoon WM. My, over 50 years ago, store bought barometer is showing a little over 28.80. At least the needle is also pointing to rain which is what is currently occurring. Stay well, as always …

Like a snow report from 20 years ago. Oh well

A lot of road ponding around town with this last wave of showers, shows how over saturated the ground is.

I love it! I need to find my grandfather's one from West Germany(!)

[hudsonvalley21]

Very impressive system, 3.84 since midnight along with 0.60” Sunday up to midnight gives me 4.44” for the event total.

Upton’s QPF map was spot on for MBY

Crazy flooding occurring on the Saddle River in Lodi.  Up to 7 different water rescues so far.

Farmingdale gusted to 44 last hour. Branches were swaying in my backyard but not as bad as before. Cleared up fast however once rain ended.

I’ve lived on the beach in Wading River since the mid 80s. Our worst damage was never summer hurricanes, but winter noreasters. The hurricanes are less frequent and tend to be weakening By the time they reach us. The winter storms are strengthening as they reach us and cause huge amounts of erosion

[nycsnow]

400k without power in Maine wow

In Long Beach the ocean came up to the boardwalk dunes. Looks like severe erosion. Would have been much worse if high tide was 5 hours earlier.

Snowmelt from the mountains (where there’s also upslope heavy rain on S winds) is adding to the flooding downriver. Models pegged those mountains to get crushed. Yep, terrible situation there.

Few branches down, not as bad as expected here wrt tree damage.

Winds did shake and break gazebo horizontal support.

Yeah, pretty rough conditions up there today.

 

 

[keno19]

I was let down on the forecast of 2-3 inches of rain and 60 mph gusts.  Im here in  south Nassau and my highest wind gust was 29.1 mph and rainfall for the event was 0.91 inches.  My tempest weather station is 25 feet above the ground nothing blocking the wind.  I am trying to figure out if the storm wasn't as powerful in my area or is the tempest weather station not accurate on wind?   i know its not accurate for rainfall do to false vibrations from wind.  anyone have any suggestions or ideas on this?

We were east of the low so generally had less rain. I had about 1.5” which I’m fine underperformed given the deluge last Sunday that flooded out Jericho Tpke for a whole day. A good amount but not severe tree damage in my area, so winds probably got over 50-55mph but not 70mph like some models had which as most pros pointed out was overdone. Also pretty severe beach erosion, thankfully high tide didn’t happen during the worst conditions and the lunar phase didn’t enhance the tides. 

[TriPol]

As afraid as we all were for the wind and rain, the area bore the brunt of the storm well. Mass transit was a mess, but besides that, no major issues.

[JerseyWx]

Over 5 inches here, really more than I expected.  Lot of roads closed and backed up, including parts of route 23. 

Need to dry out for awhile now, been too wet of a fall.
