Seriously, It's pretty cool outside. I don't know if/where the air temp factors into the tropical/subtropical thing, but this feels more like a fall/winter noreaster than a tropical system. The cloud cover is the same way, tropical usually has some breaks of sun, but it has been totally overcast all day.



I agree I am in Morehead too and the temp is in the hi 60's like 68 i think when I last cked, the wind is blowing like crazy no rain yet this does not have the hot humid tropical feel, i do know my sister was called into work for the whole night she works for a local elect co. i just read where some of the down east schools were sent home early, tropical or no tropical we are getting a storm and it could be a good one, so far its been more than we got out of hannah, i was at the beach almost the whole time during that it was nothing wind wise or rain, i'm headed to newport in about a hour and im sure ill have to fight the wind blowing me all over the road going home. then off to the beach tonight, hey has anyone heard who will be here from the weather channel yet? I enjoyed Jim Cantore during Hannah

I think subtropical with a very weak warm core. The convection needs to reform over the LLC. I say 50/50 shot at upgrading by 11pm.


They likely won't have a conclusion by 5 pm, but I think it will be upgraded between 6 and 8 pm in a special advisory.

Well, it's certainly not tropical. They'll look at the temperature difference inside vs. outside the center to see if there are any hints of a warm core.

It will be named Kyle, because it's surely subtropical, but not tropical. But it doesn't matter. It only needs to be subtropical to be named.

so the dutch are reliable and the Germans arent.. :wink:

Even so Me and Wxman57 see this as a subtropical storm. I believe the nhc won't upgrade with some minus 70 or 80 convection exploding over that center...It looks a little thin right now. We will see, because I could be proven wrong with a Advisory at 11 tonight.

Ferry runs canceled due to weather

NEWS-TIMES
Published: Wednesday, September 24, 2008 2:08 PM EDT

RALEIGH — Due to high winds and water, the N.C. Department of Transportation's ferry division has canceled its afternoon runs between Swan Quarter and Ocracoke, Cedar Island and Ocracoke, and Cherry Branch and Minnesott Beach. The Currituck-Knotts Island ferry will end service at 3:30 p.m.

Recon seems to be in the storm at 300mb - I guess it wants the upper level temperature first?

Note the wind directions at flight level - ESE-SE winds well southwest and west of the surface low center in the sam place that surface winds are N-NNE at 35-45 kts. Points to a mid-level center well southwest of the low level center.

wxman57 wrote:Here's an 18Z surface analysis. Note all the 30-40 kt winds south of the low blowing away from the low center. Plenty of cool, dry air around this low, so it won't likely become tropical before moving inland tomorrow night. Certainly looks as "subtropical" as any other such storm the NHC has named in recent years. I really can't fathom why they can't bring themselves to name it without a plane in it first. Of course it's not tropical, but it may produce winds near hurricane force over the next 24 hours.

You and JB agree. Small snippet of his column shouldn't violate terms of service agreement...

You know what is really going to tick me off..when in 5 days they name the monster that is going to develop midway between Bermuda and the Azores It will be exact distance from any land mass that can be effected within 3 days, of origin in the non tropics, and it will get named.

It's close enough and I expect STS Kyle, they have to beef up the #'s a little because 7/4/2 does not look good for the remainder of the season. JMHO

Water over nc12 on Hatteras Island and in Carteret County at Cedar Island. Water over roads in Craven County and Pamlico County as well. Forcasts are calling for 4-6 feet or more of flooding on south end of Pamlico Sound tonight and tomorrow. Winds gusting to near 40 mph.

Whatever happens with 94l, the winds have eastern NC already underwater. If it develops, even to a strong STS/TS or minimal hurricane, the flooding will be the same as a hurricane, because the water is already piled-up on the west and south ends of the sounds and in the rivers. Not a good scenerio at all.

Thunderstorm cluster North of the smaller thunderstorm cluster over the center just barfed out a semi-linear outflow boundary that is heading Southward towards the center.

I wonder whether that will rev 94L up, or just disrupt it even more.

Starting to get really windy here around Emerald Isle. Already had some gusts to around 50 mph. Local Mets are saying there's already 4-6 feet of flood water and that it probably is going to get worse as what we're getting right now is from the gradient with the high not the storm itself.

This is what David Roth from the HPC said on Wikipedia.

"Oh, heavens no, at least not anymore. NHC made a change in the hurricane and subtropical cyclone definitions in 2004/2005. Any subtropical cyclone which reaches 65 knots is deemed a hurricane. Also, subtropical cyclone type B's (neutercanes) fall under the tropical cyclone category. Another subtle change that confounds interpreting the database. I think HURDAT should have its own midrash or Mishna. Oy!"
