End of September update: The North Atlantic flurry dominates the Northern Hemisphere ACE contribution. But the lack of Pacific activity keeps the NH and global ACE still at 30-year lows. Basins with respect to previous 30-year-to-date averages: Western Pacific 25% Eastern Pacific 44% North Atlantic 164% Northern Hemisphere 63%  If no additional Atlantic ACE occurred, 2010 would rank as the 18th most active since 1950
