I think this calls for a poll to be created on the status of 94L. The options should be extratropical storm, subtropical storm, tropical storm.

Tropical storm...
1# Tight innercore
2# Well defined warm core
3# Well defined wind core

Maybe not the best on earth, but one at that. If this had another 12 hours it would form a CDO over its core.

Over the past few hours we've had absolutely torrential rain bands come through, some tornado warnings, gusty winds. At one point my place was shaking and I couldn't see out the window. Nothing major, but pretty close to what hanah was like.

Should've been named, period.

I'm sure the arguments at NHC were even more lively than on here.

This was interesting to say the least. It felt tropical here today, conditions much worse than Hannah.

And we actually had a minor storm surge in Carteret County at about 8pm tonight! Very rapid water rise along Bouge and Core sounds. Flooding reported in Salter Path, between Atlantic Beach and Emerald Isle. Also flooding reported in down east areas of Carteret County. Water up to homes (but none reported inside homes) in Smyrna, Williston, Davis, Stacy, and Harkers Island. US70 east of Beaufort had water over it in many places, deepest reported was about 1 foot deep. NC 12 at Cedar Island was overwashed, and I heard that NC58 in Salter Path was covered but still passible.
This surge came in rapidly, and receeded just as rapidly, with the peak flooding taking place over about an hour to an hour and a half. And it pretty much co-insided with landfall, and was exactly like the surges we always get with a landfalling system around Cape Fear, although this was not as severe.

I have been through many hurricanes, tropical storms, and nor'easters on these southern outer banks during my 45 years, and the ONLY time that I have seen and felt these conditions were with tropical systems. This just did not feel or act like a noreaster. Yesterday, on the other hand, DID feel like a noreaster, and not a tropical system. Very strange event indeed! I'm not an educated meterologist, I can just tell you what I have seen and felt. So take this commentary for what its worth. :lol:

I am sure,they will look at the data when the post season analysis comes and conclude one way or another that this was somekind of tropical or subtropical system,or the post season analysis concludes that it was all the time extratropical.

We just had a confirmed 43 mph gust at lake Moultrie. There is a strong band making its way through Berkeley county, with torrential rain moving into Cainhoy. This is much worse than anything we got from Hannah. I think the NHC blew it on this one!

we have had some thunder squalls move through here tonight and the sound has relaly risen--I agree this should have been a named stormed--there have been named tropical storms that have passed by without this much wind surge or rain

Temp in Pitt County rose significantly over the course of the evening. When I went to work, there was a cold breeze. Now it's warm and humid. We got an occasional gust today, but I really wouldn't call it windy here. It has rained off and on all afternoon and evening. Dramatic lightening started around midnight.

Wilmington, NC, had its high yesterday at 10:32 PM EDT. Interesting!

Which begs the question, if the system was non-tropical, shouldn't the temperature have descended?

The image shows temperatures (°C) as measured yesterday on the AF307 02GGA flight, during the time the plane was flying at 200-300m height.
Highest temps were measured when the plane came in (from W side), 23,0 - 23,5° in an area extending to 40 km W of the center. Further all temps between about 21,5 and 23,0. Only some 50 km SW of the center temps dropped below 20°C. After passing the center again, plane went NE and temps were steady between 22,0 en 22,5 until the plane ascended at some 150 km NE of the center.
So a broad area without significant temperature differences.
