The UK Met Office has released their 2009 July–November North Atlantic Tropical Storm Forecast, calling for 3 – 8 storms, with 6 being the most likely count.  The M.O. was highly accurate last year, predicting between 10 and 20 named storms, with 15 being most likely.

 

For the first time, they have also released an ACE forecast (Accumulated Cyclone Energy) for the North Atlantic.  ACE values are predicted to be between 40 and 80, with the most likely value of 60.  The long term ACE average is 131.
