txmesh watches official government feeds and, when dangerous weather or river flooding hits a mesh's area, sends a short warning to that mesh over the radio. This page shows exactly what we watch, what sets off an alert, and where the data comes from. You can also ask the mesh yourself at any time: send !nws (active weather alerts) or !flood (river gauge status) on the #bot channel and the answer comes back over the radio — no internet, and no waiting for an alert to fire.
Alerts stay inside the mesh they belong to. Each mesh watches its own list of counties and river gauges, and a warning that matches goes out only over that mesh's own gateways. A Travis County warning is transmitted by Austin Mesh radios; a Dallas County warning is transmitted by North Texas Mesh radios. Nothing crosses over, and adding a county to one mesh never puts traffic on another's airwaves.
On the radio instead of the web? Send !nws or !flood on the #bot channel and your mesh answers with the same data — any time, whether or not anything is currently active.
Each block below is self-contained: the counties and gauges listed for a mesh only ever produce alerts on that mesh's radios, on the channel shown. If your county is listed under a mesh whose radios you can't hear, you won't receive its alerts — ask us about getting your region covered.
