What sort of _technical_ solution might exist to this problem? Likely __hightly__ targeted mobile device alerts. Localize to cell tower and maybe even quadrant and issue warnings like "You are in a flood plane that might experience a flood based on heavy rainfall." It can't be like the 'smoke alarms' which I've been trained are just 'battery eating middle of the night awakeners'. I've only _only_ ever had those go off because it's a low battery, or on a muggy hellish night because it cooled off enough for the relative humidity inside to become condensing. False alarms literally Pavlovian train someone that it is not an emergency, it's an annoyance.
