• A student is looking for help on tropical cyclone prediction. Please fill out the survey linked to this thread: https://stormtrack.org/threads/storm-and-hurricane-intensity-prediction-survey.32957
  • After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

Can it maintain the strength?

I think right now, the eyewall has weakened as it is in the ERC phase (eyewall replacement cycle), judging by the IR satellite images. Given the distance from shore, the hurricane will likely replace it's eyewall right before landfall... I would still venture to say 155KNTS at landfall (175MPH), with gusts over 200MPH.

What does the Eyewall Replacement Cycle Do?[/b]

it reorganizes

Eyewall replacement is when superheated stratospheric air is ducted down adiabatically into the core of the storm. If you are in the space shuttle at night, you can see spetacular ion burst flashses, when the air exceeds its maximum bernouli coefficient.
 
I think the 175mph measurement recorded today will be the highest speed of this storm. I think it will weaken to around 145-150mph as it lands. My reasoning is based on the increasing SW shear associated with the weakness/trough in the upper levels. It is already evident that it is having at least a slight effect on Katrina with the recent weakening and especially satellite IR analysis. The next couple of advisories will be interesting.

Still....150mph would be devestating and a major catastrophe for the region...especially with the large size of the storm.

I tend to agree with the overall idea, however I think that the decrease in the strength will be slightly more subtle, to around 160 or so.
