Timeline of the 1991 Atlantic hurricane season

The most destructive storm of the season was Hurricane Bob, which brushed the Outer Banks of North Carolina near peak intensity on August 19, then made landfall twice in Rhode Island later that day.

[4] Bob killed at least seventeen people along its path and caused extensive damage in New England, totaling $1.5 billion (1991 USD); this made it one of the ten costliest hurricanes on record for the United States at the time.

Its strength and large size created an enormous area of high seas over the western Atlantic Ocean during late October and early November.

[8] Six of the fatalities occurred when the Andrea Gail and her crew were lost amidst the treacherous conditions; the events surrounding her sinking inspired Sebastian Junger's 1997 book The Perfect Storm, which was adapted into a 2000 film of the same name.

Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest five units (knots, miles, or kilometers) and averaged over one minute, following National Hurricane Center practice.
