I wasn't here then, but I suspect the complaints were targeted at the
data source, but were in fact the problem of IGate operators that
configured their IGates to transmit alerts for a much larger area than
their reasonable RF footprint. It's easier to shut down the source than
to "fix" a few (tens? hundreds?) of IGates that might not have even
supported sufficient filtering capability to even stem the tide of messages.
The weather alerts as specified at http://www.aprs-is.net/wx/ don't
actually include any actual APRS-aware location, but only an NWS office
designator. You'll note that the t/n (NWS weather type) filter isn't
supported in the .../call/range form. So, there's no defined way to get
"local" NWS alerts from the APRS-IS feed for gating to start with. The
filters are all-or-nothing.
I'm trying to figure out a way to support a filtered gating of such
information for any IGates running APRSISCE/32 and they'll probably be
based on the NWS office being explicitly specified in the filter
component(s).

That's a shame. I don't know why someone would have a problem with a weather
alert. But what's worse is that someone would get harassed for providing a
service like weather alerts. Can't the alerts be turned off on the clients?

Does anyone know the status of Weather Alerts here in the U.S. ?
We have had a few Tornado warnings here in Central Florida today, but no
alerts
coming across from APRS-IS.
The original wxsvr server that gated WX alerts from NWS to APRS-IS was taken
down by its maintainer qhite a while ago. A replacement server was put up
by
Pete Loveall, but he made a decision to gate only alerts that were immediate
warnings from NWS, unlike the prior server that gated all of them.
Apparently the owner of the previous system had taken a lot of heat from
people
about too many non-APRS alerts being gated, so when Pete stepped in to fill
in
the gap, he chose to be much more conservative in what he gated.
Unfortunately,
that means that very few NWS alerts really ever show up on APRS in many
areas
--- unless NWS designates the alert as an immediate threat, it doesn't show
on
APRS. My area is one that went from having a number of WX warnings all the
time (high wind, high fire danger, dangerous thunderstorms, winter storms,
etc.) to almost none.
There's really nothing to be done for it other than for someone else to put
up another wxsvr replacement with a less-conservative gating policy and be
willing to endure the flaming from those who object to wx data on APRS.
