Monitor page
for changes
    
   it's private  

by ChangeDetection

Enter your email address above and you will receive notifications from the ChangeDetection.com website whenever this page is altered. Instead of entering your email you can visit the site and read all their privacy info if you wish. Just copy the URL to this page so that, if you decide to get alerts, you can paste it into their forms at ChangeDetection.com. Or, if you decide you trust them, you can just return here and enter your email address.

Be ADVISED, this page is generally updated infrequently from 14 to 6 days prior to flight. Maybe once every other day. Starting around 6 days prior to flight I attempt to update it at least once a day. Other than that, it is very infrequently altered. Each alert comes with an unsubscribe link. So, if you get tired of being bombarded, you can easily stop the monitor.


Notes:

1.) Errors - On rare occasions there are errors noted in the data file downloaded for the prediction. The errors are identified on the server end, not on the Balloon Track processing end. When I see this type of error I will note it in the prediction. If the resulting forecast makes no sense, I'll not post it. But, if the resulting prediction does fit within the parameters of  a series of other predictions I'll probably post it with the warning notation. So, if you see a prediction with a warning tag, consider it suspect but possibly accurate.
