WSI Issues Updated 2009 Hurricane Season Forecast
Weather Authority's Tropical Forecast Continues to Call for a Relatively Quiet Season This Year
Andover, MA, May 27, 2009 — WSI Corporation’s updated 2009 hurricane season forecast continues to call for 11 named storms, 6 hurricanes, and 2 intense hurricanes (category 3 or greater).
These forecast numbers are the same as the previous WSI
forecast issued in April due to a continuation of relatively cool tropical
Atlantic Ocean temperatures and a trend towards El Nino conditions in
the tropical Pacific. The 2009 forecast numbers are quite close to the
long-term (1950-2008) average of 9.8 named storms, 6.0 hurricanes, and
2.5 intense hurricanes, but are significantly lower than the numbers from
the relatively active seasons of the past 15 years.
The 2009 WSI tropical forecast comes on the heels of a very successful
2008 forecast. The WSI December forecast values of 14 named storms, 7
hurricanes, and 3 intense hurricanes were slightly smaller than the final
observed 2008 values of 16/8/5. The subsequent updates improved the forecast
further, as the April 2008 updated forecast values of 14 named storms,
8 hurricanes, and 4 intense hurricanes were the most accurate amongst
the publicly-available forecasts issued last spring.
“Ocean temperatures in the tropical Atlantic are
cooler, relative to normal, than at any time since 1994," said WSI
seasonal forecaster Dr. Todd Crawford. “Further, the recent La Nina
event has now ended and a trend towards El Nino conditions has begun,
and because of this we expect at least slightly above-normal wind shear
in the tropical Atlantic this season. Neither the cooler tropical Atlantic
nor the expected wind shear conditions are enabling for tropical activity
this year. While we have persisted our forecast numbers in response to
the latest information, future changes to our forecast are more likely
to be towards smaller numbers than larger numbers.”
