[EAS] The California Fires - Another view

[Botterell, Arthur@CalOES]

Yes, that's a common story nowadays... not altogether without justification, as if you need to alert folks in an open space like a public park, there's really not a lot of ways to do that.  Different situations require different tools... its why no single golden-bullet technology can ever be The Answer to public alerting.

The practical problem with sirens is finding the "Goldilocks Zone" in sound pressure levels between the minimum for people indoors (or at a distance) to hear the siren reliably, and the levels at which birds start falling, stunned, out of the sky...

The cool aid they always try to serve up to me is that the sirens are intended for folks who are outdoors.
Working, playing outdoors and not near a radio or TV.
They were never intended to warn people who were indoors. YMMV.
