That northern vort really has a nice spin to it.

#NOAA42: Doppler analysis from first pass in #Isaac shows circulation doesn't extend above 8 km altitude. Easterly winds above that height.

Not going to do much until that easterly calms down... Especially at 5 miles above surface.

You're saying they sampled the whole storm already?!

They did one pass at 10,000 ft before dropping down to 5,000 ft for pass #2. They are starting pass #3 right now...so basically yes.

Where is recon going, seems they would want to travel SW Are they turning back to go SW now?

sure does, look like WNW or perhaps north of west...

I remember a dumbbelling Hurricane Gilbert strengthening very quickly after scraping off northern lobes over Haiti.

Don't think so ... Gilbert was in a steady state of strengthening at that point and rolled south of Haiti.

Nope; I watched it happen.

Gilbert's problem wasn't decoupling but rather a very intense feeder band stealing moisture. The system was a top-end TS or low-end cat-1 at that point, but had been puttering for half a day with a three-quarters closed eye. Then it scraped off the feeder convection over Haiti; and the center firmed up nice and round before clocking Jamaica at about 120mph, IIRC.

2nd pass was was lowered to 5kft to do a center fix for NHC... there back doing there research mission. ANY EASTERLY wind at 4 km is not going to allow any storms to circle the center. Basically, will continue to see storms flare and fade... if the surface slows down more, then i expect will see a CDO form... until then, just like the EURO had the last few days... this system to me and gonna keep wobbling along so to speak.

*just in from Kermit* #NOAA42 #Isaac: On east-west pass, lightning display here. Winds at flight-level from east, suggesting flight-level center is south of us.

To those observing a spin, vorticy, MLC, or an area you think the LLC will relocate, can you please give some lat/long's??? There are so many things spinning it would be easier to know the exact spot!! Thanks...

Just checked the 10 day forecast for my home town on The Weather Channel, and they say we need to watching the Tropics for Thursday. Just look up the zipcode 70526 and do the 10 day forecast to see it for yourself.

Says the same for Orange, Texas for Thursday. Covering all bases I guess.

I don't want to bog down the board with this back and forth ... but facts do matter. When Gilbert "scraped" past Haiti, he was a Category 3 hurricane. I watched it also. In fact, I covered Gilbert for the newspaper I worked for at the time as a reporter.

Can somone post a pic of where the MLC is?

Was a 1 SE of Haiti, then jumped to a 3 as it got closer and passed on by.

I'm an amateur's amateur ... but it still looks like a large, disorganized mess. I thought it was more impressive last evening than now.

[DoctorBoudreaux]

Please stay away from Texas. We don't need another "Isacc's Storm"

Okok....you say "Haiti"; I say "Haiti" and actually mean "Dominican Republic".

[ROCK]

got to hand it to the HH guys out there right now....We are really getting our moneys worth with these flights. I am sure they are all going to need a 12 pack of Shiner after looking at all these vorts....spin around each other...Kudos to those guys...

[Snowmarathon]

Conditions sure have been rough this year for these storms to ramp up......any intensification is like watching paint dry.....Remember 05'...those storms were bombing out overnight....ie Wilma; depression to cat 4 in 36 hours

It didn't scrape by Dominican Republic. It was a good 2 1/2 degrees south of there at the time it strengthened to a cat 3.

I think someone in Haiti pulled out a VooDoo Doll of Isaac and twisted all his members!
