ATL: ISAAC - Recon Discussion

[brunota2003]

They're almost a mile apart (AF is around 5,000 and NOAA at 10,000). However, a lucky dropsonde might find the AF plane. Might be why they looped away.

Oh ok,that is good to know.

No eye yet according to the latest VDM.

Wish recon would fly into the convection to see how strong the storm is.

Sorry for double posting.

The flights will be running a flight plan on where they want to fly into...they may get it at some point.

[Chris_in_Tampa]

Yep. I'll be here all night. Sometimes I get delayed a little bit creating an image. Doing a lot of things at the moment, so I get side tracked.

[chaser1]

can someone give me an idea when the next vortex message is scheduled?

[Chris_in_Tampa]

2AM EDT. But since they will want to try to have it in before the 2AM advisory, probably shortly before.

This one finally came in from pass #3:

And also for that sonde, something the vortex pressure does not factor in:

Code: Select all

Level   Wind Direction   Wind Speed
996mb (Surface)   350° (from the N)   23 knots (26 mph)
981mb             345° (from the NNW)   24 knots (28 mph)
950mb             340° (from the NNW)   19 knots (22 mph)
927mb             340° (from the NNW)   22 knots (25 mph)

Surface: 996mb (29.41 inHg)

[Chris_in_Tampa]

Good luck, I'll take them over from here.

[Chris_in_Tampa]

That was an interesting mission, next one could really be interesting. I might not be here to cover it. Might try to get some sleep.

Next AF Mission:

A. 27/0900,1200,1500Z        Fix Time (5AM, 8AM, 11AM EDT)
B. AFXXX 2609A ISAAC

D. 25.6N 82.6W
E. 27/0830Z TO 27/1500Z      Time on Station (4:30AM to 11AM EDT)
F. SFC TO 15,000 FT

Looks like recon is showing this system as beinmg just east of the track, small difference can make lrge differences at this stage of the game...

[Dean4Storms]

Looks like AF hit the center with NOAA off just a bit.

Sure enough especially if it continues or grows, any deviation to the east for now could be enough to cause it to feel that trough and turn more northerly as ECMWF had been depicting. You can clearly see in the images on the Recon thread the black track line and the drops just to the east of it.

Next flights into Issac are scheduled for 10am take off out of Ellington field here in Houston. Five planes here now. They are expected to stay here till landfall, unless of course, Issac comes our way.

[Chris_in_Tampa]

Next AF plane has taken off. Someone else can takeover. See recon data from most recent AF mission that just concluded for some unflagged SFMR data was among other suspect data that was high. No flight level winds were ever hurricane force.

[KWT]

Can I just say this a sterling job from you guys!!!

[Chris_in_Tampa]

Thanks.

Not sure if it means anything, but TWC just reported the 70kt SFMR reading. But they didn't mention anything about it being among a lot of data marked suspect.

[tropicwatch]

That is an odd turn, is she heading back home?
