Fwiw, I stopped looking at them when I got the 4th or 5th one. I got good at sliding to unlock and silence the alert without even looking.
Once I found out that I could disable them, I turned them off entirely.
I'd be more okay with them if they didn't all use that horrible klaxon noise. That noise usually indicates an immediate threat to life, which doesn't feel appropriate for Amber or Silver (which indicate a potential threat to a particular person's life in a rather large area). Save the klaxon for "we're getting nuked" and tornadoes.
