Here's an impressive satellite record of Hurricane Irene's path, including over Long Island. Irene was significant in that it did quite a bit of damage to our power grid, but also because tropical weather systems exert a good deal of influence on the ocean's mixed layer and vice versa. Hurricanes are enormous heat engines, almost a "pressure relief valve" for the atmosphere.
The statistical peak of the Atlantic hurricane season is right around September 14, not in August as many people suspect.
