Low Area Heading Toward US
02:00 PM EDT - 26 October 2000

There is a low pressure system moving generally toward the west or westnorthwest north of the Bahamas approaching the US. It will probably head more north and northeastward later on before it gets too close, however. Right now it can be considered a non-tropical low system. Hurricane Hunter aircraft are on the way to check it out, needless to say it could bring nasty weather to the east coast of the US or Canada in the form of tropical or non-tropical storm. In fact, a non-tropical system has a much larger windfield (although normally nowhere near as strong as a hurricane). It could convert itself into a subtropical or tropical system, so we will be closely watching it.

Tropical, Subtropical, Non-Tropical... place your bets.

Uh,,i hope more people come back to this site,,
and post. Mike,,I feel this will go N and NNE and
bring maybe heavy snow and heavy rain to Maine or
\Newfoundland. I cant see any evidence of a w
or wnw movement. Reply if you find time\\

I wasn't clear on that, you are right. I changed the main article to be more clear on those points. I wasn't calling for "landfall" in the Us, more of just the possibility that it could see some effects if the wind field expanded.

MULTIPLE CENTERS (#3)

If you check out the latest GOES you can see three centers, but appears the main one is south of the main convection, and is moving somewhat w of north, don't know what the NHC will do with it...based on recon it is definitely a s/t storm, not sure it is organized enough yet to be a ts.

hey bill, you probably know more about this stuff than me.. could you explain why you think this system is tropical? im not sure what makes the difference.. as for it being warm core, yeah, i guess 20c is warm for flight level (850mb?), but does this alone make the storm tropical?.. and aside from the convection being really lopsided, why arent they calling the thing oscar now? really this question is from a met. undergrad to anybody out there who can explain this to me...
somebody please inform. also, how close do yall think 95L (they WERE calling it 98L) is coming to the nc outer banks? im guessing close enough to kick the winds up to gale force at hatteras. its been edging to the left of north today..

I think what's really holding them back from starting warnings is the lack of convection over the center, its asymmetry, and the poorly-defined low-level center, with apparent multiple centers.
If convection were to fire up over and wrap around the center, I'm sure it would be upgraded.

i just keep thinking of leslie, and how they couldnt find flight level winds to gale force half the time, how the convection was always east of the center like a frontal band.. it was just a low cloud swirl other than that. does anybody notice the discrepancy? multiple centers, well, leslie did have a nice clean cut little vortex, but.. BERYL. doesnt matter. for our storm center... recon arrives at 8am eastern, so by late morning we should have another vortex message to debate. the new outlook just came across.. still just a 'non-tropical low'. with a flight level temp at 70F, a central pressure around 997mb, and 60 mph winds.. just a typical cold core system. yup.
well, enough of this fuzzy science. yall take it easy. gotta go take some more tangos down.
i never say it, its a sort of unspoken no-brainer, but great site. that goes to the guys who run it and the folks who post. ive learned a lot, especially from listening to you veteran storm watchers; and i appreciate your insights and advice.
muchas gracias.

Tropics (#8)

Outside of the low in the Western Atlantic, seems like things are pretty quiet in the Tropics. Looks like the "surface" circulation that was at 30N/71+W is rotating around a broader area of low pressure. Cloud tops don't look all that cold right now, so Oscar doesn't seem likely at this point. Only other area of casual interest is in the SW Caribbean; actually it's really south of Panama in the East Pacific. Models a couple of days ago were developing this system, but backed off, mainly due to the predicted hostile upper level environment. The MRF still shows a weak low coming into the SW Caribbean, then struggling. There is some deep convection south of Panama that is associated with a weak low which, if it crosses Panama, may have some potential to develop. Upper Level winds are not terribly hostile right now, and may actually relax over the next few days. Anyhow, it will be interesting to see if the models show this feature developing again. Anyway, i'm bored, it's lunchtime, and there's not much else to write about now, 'cept those damn Yankees! Cheers!!
