I've been through several hurricanes. Photos are important after the disaster for claim purposes. It's amazing how locked up insurance companies are and how they try to get out of everything. Photos help a lot. Just like anything out there, if you want to put things in your favor during a bad situation, have documentation of it, and photographs and video are profound in that sense.
Also, most people I know here in Florida that have been through a few hurricanes and took loss do like to look back, remember their story, share it. There's a lot of people who live here and in 20 years never even see something, so they don't believe it can happen to them living on the coast, then bam, it happens.
As for drones, drones are super useful during times like these. Inexpensive ways to see damage, potential victims, potential disasters (like a forming big sink hole), and it doesn't cost whatever fuel is in a chopper. Obviously flying it around with other vessels is not a good idea, but if there's nothing in the sky, it's a useful tool. Also again useful for later for people in your neighborhood for claim purposes. Rules are rules, but honestly you have to look out for yourself and others during bad times, Uncle Sam and the Insurance companies are in bed together and while they will help you out, there's a lot they won't do unless you fight for it with evidence. Heck the military uses drones for surveillance because its just so efficient and inexpensive.
And of course, stay safe, hope everything goes well for everyone in TX.
