ATL: ARTHUR - Post-Tropical - Discussion

[Kingarabian]

TropicalAtlantic recon program (with the Google Earth plugin) which automatically decodes the recon data. Not sure if gusts or sustained, depends on what dropsondes typically measure.

Where can I find the raw dropsonde data? Is it reported on the NHC site? And thank you for the explanation RL3AO.

I don't think that 89 KTS reading was accurate.

[RL3AO]

So am I correct in assuming the NHC completely blew it by not issuing warnings by now? It's pretty clear that the eyewall of a borderline category 1-2 storm is getting mighty close to an unwarned area.

If they thought Wilmington needed a warning they would have issued it by now. They are still probably confident that the area not in the hurricane warning will not receive hurricane conditions.

Is this of use, ravyrn. No idea what it is but it might mean something to you.

If its no, I will keep searching.

A decoded version of that sonde and its location:

Note: Sonde has since been corrected for direction from eyewall released:
Dropsonde Location: Dropped in eyewall 045° (NE) from the eye center.

I understand what they think, but hell, look at that center fix that was just posted. Just one more of those and the eyewall of a strengthening hurricane is right over an unwarned area.

Well I'm not at the NHC. However 1) They are under a watch. 2) They will be on the weakest side of the storm.

Yes it is on NHC's site. However this will show the latest from the NOAA flight and the AF flight. If you just want the latest from the AF flight into the eye, use this.

Okay, thanks. I just found the dropsondes on Google Earth are the little telescope looking icon. Learn something new every day!

Here is a little tutorial I have on those images in the program:

The new system I am working on will have a better tutorial.

EURO Ensembles are further WEST as well, NE sees Arthur.........per wxbell

according to the NWS page for them they are under tropical storm warnings and a hurricane watch. and a tornado watch

Long Beach, NC may be the first land location (besides Grand Bahama Island a few days ago) to get a glimpse of Arthur's centralized convection.

[Aric Dunn]

more and more wobbling closer to south port and wilmington... not too much longer more


just did a pretty good jog to the NNE

[Hurricane_Luis]

Latest plane has just gone over the Florida coast 390 kilometres south west from the centre of Arthur.
