Hurricane Alex first January hurricane since 1938

A rare weather system hit the Atlantic Ocean this week and it's an event that has only happened a handful of times in the last century and a half a hurricane in January.

This week Hurricane Alex developed, starting as a disturbance as it crossed Bermuda and intensifying to become a hurricane with 140 km/h winds, saidmeteorologist Jean-Marc Couturier.

Couturier, who usually spends his summer months with the Canadian Hurricane Centre, saidthe last time there was a tropical cyclone over the Atlantic was 1978 and the last January hurricane was in 1938.

Typically hurricane season runs from June to November, with the occasional storm in May.

"It's definitely against normal behaviour," he said. "There areonly five instances in about 160 years of data. Five instances of tropical cyclones over the Atlantic in January."

Couturier saidthe Atlantic provinces should not feel any direct effect, although there will likely be some large waves off the coast of Newfoundland and Labrador coast early next week.

On Friday afternoon, the U.S. National Hurricane Center in Miami, Fla., said the meteorological society in theAzores, in the mid-Atlantic,had ended the hurricane and tropical storm warning for the Portuguese islands.The downgraded storm is now moving north.

Couturier saidthe storm is likely tied to the ocean and atmospheric currents affected by El Nino.He saidthere are currently coldair temperatures and warm sea-surface temperatures over the Atlantic Ocean.

"But because we have those cold temperatures aloft, we're able to sustain the convection that's required to sustain a hurricane so it's full steam ahead," he said.

It'smore common to see extreme rain or intense snowfall events in the wake of El Nino,Couturier said. But he doesn't expect to see other hurricanes this winter.

"In the past few months, with El Nino being as strong as it was, now it probably is a bit on the decline. During the next few months its effect will continue to decrease," he said.
