New recon fix [Re: ShanaTX]
      #25741 - Sun Sep 12 2004 02:10 AM

Slightly weaker at 915mb, but that's picking nits. Ivan may be going through an eyewall replacement cycle again, as the recon notes that the current eyewall is weak on the south side (20mi. eye) but that there is a secondary wind max at a radius of 33mi. Max flight-level winds in the NW quadrant were 133kt.

I just went by what the advisory said...

Guess the advisory was sent out before recon data came in?

Looks like the updated models are showing a sharp NE turn into SC after making landfall in FL. Anyone else seeing that?

Seems like they would schedule recon to be there about 30-60 minutes earlier. So the new data gets in the advisory.
I guess that's why they don't-it makes sense.

These are the CMC models I have been looking at that have Ivan the furthest S and W than any other model and to this point to me the most accurate to this point.The S side track of the NHC models are or get close to this track.If you look up the history of the CMC you will see it is awful close to this point.

Javlin, they are further west than any of the Canadian models I've seen. Grand Isle and New Orleans? That puts a lot of area in the NE quadrant!

But isn't that track based on the NOGAPS that ran over 16 hours ago? I've noticed that the latest BAM, UKMET, and GFS that were just run have it turning east much more quickly than the NOGAPS and GFDL run early yesterday. Weather Underground Forecast Models

Re:Poor initialization [Re: ShanaTX]
      #25753 - Sun Sep 12 2004 02:41 AM

the problem i have with the NHC on there models is that everytime they throw a model out it's almost going NW.If you can not get the correct direction in the first 6hrs doesn't that just turn the the whole model into trash.They fail to recognize the effect of the ridge to the N.Yea they will get it right before long a blind man
throwing at a dart board will get lucky somewhere.The ridge is going to break down is it 81' 83' let's try get a handle on that part it's not to far away geeez.

Look at the history of the model Dan every night about 11:00pm CDT Montrealboy has been posting them @ S2K.I have been watching them closely puts the NHC to shame.
Yea Dan it does and I keep saying to this point seems far W to me to but what is the history of this storm.

I mentioned this to Phil earlier. I guess it's safe now to mention it here.
Camille was forecast to hit between Ft Walton Beach and St Mark's FL. The watch was posted 36 hours in advance from Biloxi to St Marks. The warning went up 3 hours after the watch!, from Ft Walton Bch to St Mark's.
At 5 am the next day, 18 hours before landfall, the warnings were extended west to cover Biloxi.
At 9 am, four hours after the first warning extension, a second extension to New Orleans and Grand Isle,LA was issued.
Camille struck about 25 miles west of Biloxi at 11pm, on Sunday Aug 17th.
Contrary to TWC, she had an extremely low pressure also.
Measured by Navy Recon to be 26.61" or 901mb, with a max flt level wind of 190mph.
*They are totally unpredictable!! Get ready now and pray you don't have to leave. If you do have to leave, you are ready to go right then.*

Sats are back up, and Ivan has cleaned up his appearance.
The eye is smaller than earlier, and there is more outflow in the NW quadrant ahead of the storm.

The Gulfstream is also enroute to conduct High Level Recon.
