A No Fly Zone And Grocery Stores In Benghazi

I'm writing this on my Droid while on a short vacation in Paso Robles, so please forgive the short content and terse style. 

After Gadaffi's forces captured the last town, a large number of refugees were reported streaming towards Benghazi. A cease fire is as good as a siege. Just what will it be like in Benghazi two weeks from now with lots of refugees and rebels, all cut off from their normal supply lines in Western Libya? A no fly zone helps this in what way?

What will the local grocery store look like on, say, Tuesday of next week?
