Forecasters increase hurricane chances

Monday, August 11th, 2008 6:22am MDT
NOAA says there is a greater chance for hurricanes in the coming months.

NOAA says there is a greater chance for hurricanes in the coming months.

In their August update to hurricane season forecasts, experts at the National Oceanic and Atmospheric Administration (NOAA) have changed their predictions for the season and now expect a greater chance of hurricanes this season.  They are now predicting an “above normal” season with 14 to 18 named storms – up from the 12 to 16 they predicted in May.

The forecasters now believe there is an 85 percent chance that this above normal trend will take place (up from 65 percent in May). 

“Leading indicators for an above-normal season during 2008 include the continuing multi-decadal signal – atmospheric and oceanic conditions that have spawned increased hurricane activity since 1995 – and the lingering effects of La Niña,” said Gerry Bell, Ph.D. of NOAA’s Climate Prediction Center. “Some of these conditions include reduced wind shear, weaker trade winds, an active West African monsoon system, the winds coming off of Africa and warmer-than-average water in the Atlantic Ocean.”

Thus far in 2008 there have been five named storms and the most active hurricane period – August to October – is just now beginning.  Will this prediction hold true?  Unfortunateley forecasters have struggled in recent years with their predictions.  Last year NOAA predicted 10 hurricanes and only six formed. The year prior, 2006, nine hurricanes were forecasted by NOAA but only five formed.  In 2005, the year Hurricane Katrina devastated New Orleans in the worst U.S. natural disaster, the forecasts underestimated storm activity.

    I’ll be curious to see how the forecast bears out. They haven’t been too accurate in recent years.
