Lost power for about 4 hours - 9pm to 1am here in NW Chesco. Power grid really stood the test well

around here.

Top gust on the Davis here in the valley was just 35 mph, max sustained only 24.

Looking at the surrounding hilltops, and judging by tree movement and sound, 60 mph

seems reasonable around here.

Rain fall underperformed with 2.03 yesterday, storm total so far 2.48"

Barometer bottomed at 28.28 here which is likely an all time record.

Lost power for a grand total of 2 minutes total which is a miracle. Many trees down with debris as the sun rises. All my trees survived well which is also a surprise. Thought I would lose my 120' Maple last night around 11pm. Total rain was probably less than 2" total a far cry from the 6-8 we were forcast but a godsend for the river towns.

Similar conditions here...me and mine are fine...but increasingly this is my take.

Across the Northeast and in NJ/NY/Conn in particular it is a tale of two storms...in the interior it is a storm of mass disruption and moderate destruction. Widespread power outages, some injuries and structural damage and the occasional fatality by car accident or tree fall. Side by side with these serious impacts are people like you and me...people who have followed along in anticipation and anxiety but who for the most part have been mostly inconvenienced.

The other storm...is an immediate coastal storm and a tale of repeated danger, rescue and unfortunately more frequent fatalities....from Atlantic City...Toms River...the Central Jersey Shore NYC LI and now Connecticut the tale is more grim...serious damage to transportation infrastructure...a disconnect between forecasters and evacuation decision makers...communication failures. Arrogance from the near miss of more serious consequences of Irene. Here, near geographically but psychologically removed from the interior...this has been in places a complete disaster. I gather this both from posters and first responders on this board, friends and family on facebook where I have been actively posting about this storm for days...and coworkers from the union I belong to, some of whom live along the central Jersey shore. This storm surge has taken many by surprise...I can only hope that most found some sort of shelter of last resort and that our magnificent first responders have been able to assist the rest. We will find out in the next few days....but I fear this may be too optimistic. Hoping I am wrong about this....either way a lot of lessons to be learned from this storm.

Well said, Jon...

Which ones are you unsure about?

PHL's gust to 68 was between obs in the remarks (gotta learn to read METAR wink.png ). I don't know if Mt. Holly dialed in themselves or borrowed the report I mentioned here, but I dialed into TTN after the initial communication loss and got the 68 mph report. After that it lost power.

The funny part is we actually did learn METAR a few weeks ago.. I asked the prof how they differentiate a sustained wind, a gust, and a peak wind in the remarks, and he wasn't sure off the top of his head.

Sounds like he shouldn't be teaching it ;)

03034G44KT is the current sustained wind and highest gust during the last 10 minutes. 34 knots sustained, gusting to 44 knots.

PK WND 02059/0001 is the peak gust since the last hourly observation. 59 knots at 0001 UTC.

Amazingly enough, the power stayed on (PSE&G has 1.2 million outages). There were several brief interruptions, but I thought for sure it would go out last evening. I have been seeing many county highway department dump trucks going up and down the road filled with tree debris.

the 81 was false at abe?

I don't know where that 81 was from. Not ABE airport, as far as I can tell. Maybe someone from Mt. Holly can enlighten us.

ABE obs up until DCP power failure follow, you'll note the highest pk wnd remark is 02061/2306 (61 knots, 70 mph, at 2306 UTC/706 PM EDT):

Anyway, back home my parents managed to get through with only brief power interruptions. The Davis anemometer on top of the telephone support pole in the back yard recorded a peak gust of 43 mph. Considering there is a small forest located to the northeast, east and southeast of the anemometer, that's actually very impressive. Easily the strongest its gusted since its been there (though that's only been since May).

The 81 mph gust was from South Allentown (spotter or public) not ABE. The PNS has it listed as South Allentown and a 70 mph gust listed for ABE.

Does anyone know if the 81 mph gust in Allentown I keep hearing about is valid?

Yes it is valid...

I know who reported the ob and it is a pro met...

Furthermore i was outside at the time that it happened which was when a large tree was uprooted in my immediate vicinity and at that time my aunts house lost her porch roof... and her window was blown in seconds before that....

Tons of damage all over the city...

A house at 8th and turner lost there roof and it is in the street

Mcdonalds lost their roof

There were literally stop signs flying last night.....

It happened

** People need to keep in mind that Allentown is much LARGER then the airport...

ABE stands for Allentown Bethlehem Easton ...which covers a much larger area then just the airport...

We didn't get much wind out this way (WV), and that's probably why we never lost power. Precip has changed over to all snow now after a nasty mixture most of the morning. Some icing occurred (locally at 1,000 ft.) and obviously the higher elevations are buried in snow. It has rained since Saturday so the change will probably ease flooding concerns.

Some of the pictures and reports (rail cars on the NJ turnpike) coming out this early and the ones from yesterday are impressive to say the least. I think Gov. Christie said it best we all knew, at least on here, that it was going to be bad, but not this bad.

Did th AC mayor just say 16 people died in AC alone?

I don't think so but it was funny to hear the one guy say the rumors that the board walk was destroyed were not true, but in the next sentence said that the sections of the boardwalk that were destroyed were old.

Hey now, he's filling in while the regular prof is on sabbatical. Cut him some slack. ;)

And in general I knew both of those, but I never realized that you could have a PK WND higher than the G. I always just assumed they were the same. Thanks!
