It does work (Score 1)

I am from cancun mexico, and we do get some hurricanes every now and then, I remember receiving text messages from the government alerting me as to the warning level color at the moment whenever a hurricane came close. It is a pre set code, so most people could figure out if they had to start checking their food and water supplies or start boarding their windows. These messages were simple enough and very informative, I believe it could work in other places or for some other natural disasters.
