T-Storm

How did everyone make out during last nights storm? Who got slammed?

[cfd95]

Good question. I heard the south shore from islip to mastic got slammed. Possible tornando or very very high winds in the Patchogue area. Heard technical reacue teams going to Hagerman for a collapsed house. Any 1 have further.

Bayport:

2 reported 13's
About 6 or 7 calls for wires down

Also alot of calls for trees down, we only went out if they were blocking the road.

West Sayville ran for hours.....we had a structure fire, several large trees ripped from the ground block roads and crushing cars....also whole tree tops breaking away from the stump and blocking doorways and driveways....We definitely experienced a downburst in the Oakdale/West Sayville area. Possibly a microburst thats up to the National Weather Service to decide. Patchogue had to experience the same, very doubtful on the tornado part because no rotation was detected with the storm cell. Several areas of the Island experienced considerably the same affects. All that damage from a thunderstorm imagine what the next hurricane will do here on the Island!

Dix Hills only had 1 wires call, and a short power failure....but the storm was pretty cool to watch

Selden had one burned up shed that came in as a house to the "rear of". One burned up TV in a senior complex. And a M/A to Hagerman for TRT.

I was watching Channel 4 news and they showed the storms moving through and they had a swirly thing on the radar and it said their radar detected storm rotation. None of the weather maps I looked at showed the same. Maybe it was a publicity stunt....

not to sound geekish, BUT. A tornado was very likely due to the extreme heat followed by a rapid cooling of the atmosphere. It could have been very difficult for Doppler or other land based detection systemst to pick up rotation due to the electrical activity associated with the storm. Similar reports of micro-down bursts were reported throughout the south shore, mainly the sayvilles, and south brookhaven. One report of a distinct line of destruction spanning about 1/4 mile. So yes, it is very possible to have experienced a tornado, although a weak F1(Fujita Scale). Long island is no stranger to these anomolies, we experience an average of 1-2 every year.

Yes it is possible and you are right with the average of 1-2 years however notable items to consider when visually inspecting to see if it was a downburst or a tornado. In this instance all trees snapped or fell down in the same direction indicated no rotation at ground level. At higher elevations aloft, it is possible for the rotation to occur but it doesnt seem like it was transfered down to the surface. Secondly most lawn furniture and other items were not blown away indicated a downburst situation. The extreme cooling caused by the front is indicative a mixing of air temperature values aloft not necessarily causing a tornado but definitely creating a large thunderhead aloft. If you take a look at radial velocity maps from that evening, Max Towards and Max Away speeds did not encompass each other setting pretty clear evidence of a downburst. Now whether a micro-burst or downburst. However LIFIREEMS insight is very true about ability of a tornado to occur on Long Island and how they aren't that obscure. Given the right conditions a tornado could wreak havoc anywhere.

I feel like the "Sky Warn" has just entered the building. So, out of all of that I'm guessing no hook echos were seen on Doppler?

Ha, nice one Chet. engine brings up a very good point with damage. Though a lot of household damage was reported in the East patch and Moriches area, the damage to the trees is key if local radar couldnt pick it up. Still no official report from NWS on the storm, whether or not a tornado or downbursts occured. generaly takes them a day or two to gather the data, possibly longer for this one due to the storm in the atlantic. Its good to see some very watchful eyes on the board. you are a vital part of the first responder community

I don't know if you guys have this, but here is the Skywarn website: skywarn.gigdot.net/

I work with a guy that's part of or runs the site.
