Active Hurricane Season Predicted

Eric Holthaus, a colleague at the IRI, has written a nice piece on the latest, troubling hurricane forecasts for the Atlantic region. First few grafs below..

The Atlantic hurricane season has officially started, and the International Research Institute for Climate and Society has issued its updated seasonal hurricane forecast for the region. The results continue to indicate that an above-normal season is very likely. This could spell trouble for highly vulnerable Caribbean nations such as Haiti, still reeling from the effects of a 7.0 magnitude earthquake on January 12, 2010. On top of this, other forecasts point to increased thunderstorm activity for the region as well.

The IRI’s hurricane forecast probabilities are the strongest the institution has ever issued at this point in the season, eclipsed only by a late-season forecast during record-setting 2005. The latest numbers call for a 50% chance of above-normal activity, 35% chance of near-normal activity and a 15% chance for below-normal activity. Put in simpler terms, this means that the chance of having an above-normal year is more than three times the chance of having a below-normal one.

The hurricane forecast issued last week by the National Oceanic and Atmospheric Administration is even stronger, calling for an 85% chance of an above-normal season.
