We came through Irma almost entirely unscathed. We lost power for about 23 hours, and for most of this we were up and running on a standby generator.

Lessons learned:

Make sure you have spare consumable parts and a troubleshooting plan for the generator BEFORE the storm. Then when it kicks on as the power fails I won't spend a couple hours running around in the rain and rising wind trying to get the electricity going to the right place (yes, it was that one breaker I hadn't checked).

Have plenty of spare hardware for the hurricane shutters. I had plenty for me, but had to scrape and scrounge to help a neighbor.

Otherwise, I think things went well. Much of this can be attributed to Irma arriving in my neck of the woods as a Cat 2 rather than 4, but also because my preps were timely and comprehensive, and the previous owner of this house planned well too.
