• 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.

Mammatus As Storm Passes Through

I had forgotten to mention this before-but about a couple of weeks ago, some strong thunderstorms came through my area. Where I live, one rather ominous cloud passed on through-no lightning or thunder. There was blue sky behind this cloud-it was moving west to east. As I looked at the cloud, I noticed some mammatus formations, not far from the westernmost edge.

So-is this fairly common? Where do you usually see mammatus-before or after a storm moves through? :blink:
 
Mammatus form on the underside of the anvil - thus often at a relatively high altitude although they can be a bit deceiving and look lower. As they are attached to the storm itself, they will follow its motion (often W>E as you described).

You can see them before or after a storm, but in my observations, I have normally observed them following a storm passage. Mammatus is frequently very photogenic, in my experience. There are many spectacular photos of mammatus being lit from beneath by a setting sun.

I can't post the image because it is a .png, but click the link below and you'll see where mammatus can occur in a generalized diagram.
