My brother and his family was on holidays in spain last year when there was major flooding, they were staying in a village up a mountain, the flooding didn't actually really hit their area, (he said they had a slight bit of rain one day) and local radio and hire car company had warned them not to drive on a certain day, but below them in lower land areas there was a lot of flooding, however their power and surrounding village's power lines were all wiped out, water was contaminated, there were bodies in flood drains your not drinking from taps after that even if it looked clear, and it was out for more than 3 days , there was no internet, wifi and pretty well no banking , there was water brought into the area by army, some people were airlifted out, but it was couple of miles away to get the water tanks- roads were mostly impassable, but luckily local farmers could get some vehicles through to water, he said the one thing they were not short of was food, everyone was lighting fires and bbq and cooking everything fresh and just handing it out , some businesses couldn't get staff in or out and they were scrabbling around locally trying to find beds mattresses etc - kids thought it was brilliant cornflakes with fanta for breakfast , time off school as they couldn't get to airport, and when they wanted an ice cream the shop owner just gave them the whole 3 litre tub , but they didn't have candles for days as the shops and restaurants gave out what they had but there was no restocking
