I find that most storms bring wind with west in it, so to kite storm wind during the summer in Miami is pretty rare.
eh, that's not really the issue. Yeah, there is some west wind, but there's also some really song east wind. During the storms it's really up and down, it might be great for 5 minutes, then it completely dies off, goes straight offshore, or starts nuking 40 knots plus. You really just have no idea what it's going to do.
I've ridden in a few of the storms during summer just to get some kiting in and save myself from going insane, but it's really not worth it
