Hurricane Bob was a Category 3 hurricane on the Saffir-Simpson Hurricane Scale. Bob made landfall on Block Island, RI on August 19,1991.


Bob formed from a low pressure area east of the central Bahamas on the 16th of August. The fledgling system moved northwestward, and became a Tropical Storm that same day. The next morning brought Bob east of Daytona Beach as a category one hurricane. The system continued to strengthen, and that afternoon; it was off of Charleston,South Carolina. On the 18th, Bob moved off of Cape Hatteras, and blasted the area with wind and rains.

On the 19th, Bob intensified to a Category three hurricane. It then weakened, and accelerated to the northeast, and that same afternoon, Bob made Landfall on Block Island,RI as a category two hurricane. Over the period of six hours, Bob moved back out to sea, near Cohasset,MA, and skirted east of Cape Ann. Later that night, Bob made another landfall, this time near Rockland,Maine. Bob continued into New Brunswick, and over the Gulf of St. Lawrence.

Bob was deemed fully extratropical by the time it crossed the northern peninsula of Newfoundland. It headed east over the atlantic, and on the 29th of August, it dissipated off of the coast of Portugal.


Bob claimed the lives of 17 people, and caused billions in damages.


On the eastern side of the hurricane, there was little precipitation. Nantucket,MA reported .02 inches of rainfall total from the storm. This has lead some hurricane buffs to speculate whether or not Bob was purely tropical at time of Landfall. The heaviest rainfall, was to the left of the track.


The name Bob, was retired in the spring of 1992.
