Two titanic forces in the global climate – and the ways they interact – will decide how fierce the storms in the Atlantic Ocean are this year.
The Canadian Hurricane Centre is predicting an average season this year, with one to four major storms headed into the Atlantic.
But meteorologist Bob Robichaud says the final figures will depend on whether El Nino, a Pacific weather system that tends to calm Atlantic storms, prevails over warming Atlantic water temperatures that create storms.
El Nino tends to decrease hurricanes, while warming water temperatures caused by global warming tend to cause more fierce storms.
