The skies will be orange and hazy over Florida by mid week and stay that way through Saturday, forecasters predict.

Another Saharan dust storm is on the way. But new NASA research is split on whether the Sunshine State will see more or less of these yearly storms that fuel red tides and many a sneeze.

One new NASA study predicts climate change will drive more frequent and intense dust storms off Africa. Another by the same agency says the opposite.

Some 60 million tons of the Sahara's nutrient-laden mineral dust lofts into the atmosphere annually, according to NASA, creating a massive layer of hot, dusty air that whisks across the Atlantic Ocean with the winds to deliver those nutrients to the ocean and plants in the Caribbean and South America.
