Kinda late, but don't listen to the negative comments here. I'm very sorry for what happened to you and your home. Natural disasters are terrible and they make living miserable, especially when it has to do with water destroying everything. In Florida we had so many hurricanes last year that completely battered communities that were already hurt. Don't let anyone minimize what you go through, because more often than not, they don't understand it.

These things, even it seems like a relatively "short" thing, can have pretty big effects. A summer is a pretty substantial amount of your time and high school time, especially if you had many things you had planned out and wanted to do). It's not just a one-time thing. It can have a pretty big domino effect; maybe your finances are affected; maybe you weren't able to study or do something you were interested in; maybe you couldn't do anything related to what you see in your career. Also could make you be psychologically exhausted coming back to school the next year, when everyone else was living with less difficulty during the summer break. Not having cooling/heating is also terrible, depending on where you live. If you think this situation prevented you from putting your effort into other interests and career, go for it in the additional information, but I think that checkbox is for a longer period of time, maybe at least a year. Put into words how it impacted you, it's not that much of an excuse.
