Researchers at Colorado State University have lower the total number of tropical storms and hurricanes that are expected for the 2009 season. Last December the researchers thought it would be an active season but subsequent predictions have been lowering the numbers. The July forecast indicates that we should see 10 named storms, 4 of which should become hurricanes. Two of the hurricanes should be major with sustained winds of more than 110 mph. Consequently, the 2009 season should be near the average numbers of 10 named storms, 5 hurricanes, of which 2 usually become major. El Nino is the main reason for the expected reduction of numbers. El Nino, which is a warming of the equatorial Pacific Ocean, causes more wind shear in the Atlantic Ocean and can rip apart developing storms. The tropical season runs until November 30. So far there have not been any named storms.
