The way the current time series is plotted makes it difficult to determine when the cell is no longer being tracked (i.e., the flash rate falls below a certain threshold). One way to see if it is no longer being tracked is to look at the Pt/time and compare it to the product time in the legend. If the product time in the legend is ahead of the Pt/time, then the cell is no longer being tracked and no more data will be added to the time series plot. Perhaps there could be a way to show that the cell is no longer being tracked so inexperienced forecasters could quickly determine this.
