I thought one of the moves the Jamaica authorities made is something one could learn from. Rather than continue providing utilities until the storm wiped them out, causing massive damage to transformers, pumps, and substations, putting the whole system out of service for weeks, they just shut down electricity and water area by area as the storm hit. Everybody knew about it ahead of time, and they’ll be able to start firing up the undamaged sectors first thing in the morning. Pretty slick idea, actually. They’ll have partial power and water back quickly, then be able to start the repairs a leg at a time.
The Islands do that a lot, but you’re right, it is a good idea. They also have the “leg power” to send people out to every home with flyers to tell them when it will happen and what to do.
*and there’s always the coconut telegraph, which knows about it before the power company does, lol*
