I'm not sure what two weeks of living expenses equates to but I know that two months of food is not enough. If you have a truly renewable source of water - that is potable and safe - then there is little to spend money on there.
You need a years worth of food stored but you also need a garden. Firearms weren't mentioned so I would say after food then a pump shotgun is in order if you have reliable shelter. If I was in the city I would put the whole $1000 into a land fund and keep adding to it until I could get some land for cash.
