Thunderstorm Ranging and Acquisition, or TRAC for short, is a sub-process in NexStorm that contains all the logic behind computing where thunderstorms are located and analyzing their characteristics. TRAC can also produce a text-based report based on its findings to show you details about individual storms. The TRAC related on map identification feature uses TRAC data to display important information about a thunderstorm. When TRAC has detected what it believes to be a structured thunderstorm system, it will start tracking it until the storm dissipates or the tracking could not be maintained for other reasons.

J-3226 is a computer assigned identifier.
- or + indicates dominating strike polarity.
10 indicates last recorded strike rate.
^ - v indicates if storm is increasing, steady, or decreasing.

TRAC will periodically generate a report based on current activity. This is called the TRAC report. While a thunderstorm is being tracked it is also being continuously analyzed. You can view the results of the real-time analysis in the TRAC report.
