• 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.

This is the first i have been able to find of the storm at peak intensity. I remember a discussion in a previous thread in regards to whether the images on NCDC website were of peak intensity (the storm did not appear to be well organized in those images). I must say, it has an appearance very similar to gilbert at it's respective peak intensity.

There always seem to be discussions on the immense size of Tip's circulation. By the looks of those satellite images, gilbert appears somewhat comparable. What is the criteria used for judging the circulation diameter of a hurricane?

It is the diameter of winds of 35 Knots (38 MPH) or greater, which is tropical-storm forced (gale) wind-field size.

Tip was about 600 miles radius of TS forced winds!!

Another definition of size is the radius of the outside closed isobar. This tends to define the limits of the outer circulation. This latter definition of size has little signal in the satellite imagery howevever there has been quite a bit of work involved in relating satellite imagery to the radius of 35, 50, 65 kt winds. 2 recent papers if you are interested:
