>>> now to what may be the best possible news for those of us hoping to get through a mild 2013 hurricane season along our already battered shoreline. a massive and sprawling dust storm in africa may suppress this year's hurricane season , at least for a while, over on this side of the atlantic. because weather patterns begin over there, and come west, and because the air mass is so big and so arid, forecasters are hoping this so-called saharan air layer will buy us some time. it already stretches from north africa to puerto rico , and there are no major storms in the pipeline. at least not yet.
