Re: Recon and Dvorak

DVORAK LATEST "2005SEP20 0145Z CI=4.4"

Recon inbound. 0205Z-Max wind (so far) at 22.53N/ 77.21W 51kts at 3164m or 10378ft.

Recon now outbound from center.
0225Z Max Wind at 23.45N/ 78.15W...59kts at 3175m or 10414ft. I know those coordinates look strange. I believe Recon came in from the NE and is flying toward the NW. That would put the Max Flt Level wind in the NW Quadrant...so far.





Thanks...I've been waiting for the recon info. Well then don't you think it will still be pretty iffy to go with hurricane strength at the 11pm? The last recon found 67kt max flt winds before the 8pm update and NHC saw no reason to upgrade from TS strength. With the westward movement you'd expect the NW quad to be the fastest winds.

Steve Gregory's blog went with hurricane strength both at 11am and tonight at 7pm (after the recon with the 993mb and 67kt flt wind), and I disagreed both times.

Now unless pressure dropped considerably and they find max flt winds like 70kt, even with the improved presentation on satellite and Dvorak close to 4.5, I don't see hurricane strength. The only argument might be to get the message out to people earlier who might not be evacuating, since we can assume it will get to hurricane strength by the 5am full advisory, but they'll all be asleep by then.
