Just scarier than usual
The sirens go off here, Oahu, for approaching hurricanes and possible tsunamis. Often there is a sub 1ft wave or a not too destructive storm. Every couple of months our phones blare with flash flood alerts which affect parts of the island. Monthly the sirens go off in tests now including the attack warning. On occasion a local siren or two go off for no reason.
Our state is often very inefficient. We feel the need to reinvent everything before deploying it even when others have a successful model.
I was not surprised we would have an error so only thought there was an off chance of casualties other than heart attacks and deaths caused by panic.
