I think these are very valid concerns, katers. I’m on the fence.
Whats tricky with flood as opposed to earthquake is that it will be a wet environment - bad for tech. Might be best to off tech completely - just syringe insulin and traditional BS machine because there will not be any way to charge a Dexcom anyway (or, even if I had a portable charger, it could get wet and full of mud if shoveling muck). It might be tough to carry a pump controller. I could use a water proof box and carry that stuff EVERYWHERE.
I think the insulin could last a week in 80 degrees, unrefrigerated. I’m a liability if I loose the insulin, so I need to carry it everywhere in a chaotic environment. I would expect heat related BG problems, but I expect those to get lost in all the problems related to intense physical labor.
As far as lacking access to food, I think I would bring those sugar flavoring packets to mix into bottled water because I’m sure they will have that. That could help with low BG.
It starts to seem like I’m carrying a lot of equipment into a mud filled house - BG machine, water bottles/flavor packets, insulin/syringes, maybe glucose tablets are better.
Covid very likely to be contracted there, I agree. It will be spreading around like wild filre.
