[aprssig] Polite to TX-igate weather warnings?

Every 5 minutes from time of origin (every minute for the first 5 minutes).  This is not a lot and AE5PL-WX specifically limits what is transmitted to what the weather service considers "an immediate, actual threat".  It was specifically designed to minimize what is transmitted and restrict it to what spotters and other 1st responders need to know when they are out in it.

One key is to keep digipeating to a minimum.  Only cover your IGate's -immediate- footprint (normally 1 or 2 digipeaters at the most).  Let other areas cover their immediate areas.

We have been gating weather objects and messages to RF in the DFW area (one of the highest APRS activity areas in the country) for over a decade.  It has been considered beneficial and no complaints even during the high activity levels (during front passage, there are normally multiple severe thunderstorm, tornado, and flash flood warnings occurring at a rapid pace).  At no time are we overrunning the RF network.
