As the system moved north, it absorbed energy from a cold front, transitioning from a tropical system into a powerful extratropical cyclone.

A tropical wave moving off the coast of Africa combined with a powerful jet stream disturbance. The interaction of these distinct weather systems created a monstrous hybrid vortex off the coast of New England.
While the Atlantic basin produced a near-average number of named systems, the quality and impact of these storms were anything but typical. This transformation allowed the storm to draw moisture from both the warm Gulf Stream and the cold air mass of the continent, amplifying its intensity far beyond what a typical hurricane could achieve.

However, the season ultimately produced 12 named storms, with 8 of those intensifying into hurricanes and 4 achieving major status, defined as Category 3 or higher on the Saffir-Simpson scale. In stark contrast, Hurricane Bob formed later in August, carving a deadly path from South Carolina to New England.
