Dust is good and bad. Good in the sense that it can squelch tropical waves and keep storms from forming in the Atlantic. Bad in the sense that these features may develop further west, once they've escaped the throng of the dust, and more readily impact land areas. This is because the low level winds -- the ones that steer the weakest features -- are generally out of the east and east-northeast across much of the Atlantic, whereas the mid and upper level winds -- the ones that steer stronger features -- will often capture something before it gets too close to the US.
