The $7 billion storm that redefined New England's coastal vulnerability
In short: Hurricane Bob wasn't just a weather event; it was a massive economic shock. By striking a densely populated region, it became one of the costliest U.S. hurricanes of its era. It serves as a masterclass in how geography and infrastructure turn wind into billions in lost wealth.
Hurricane Bob struck in August 1991, developing from a low-pressure area near the Bahamas. It intensified into a major hurricane (Category 3 or greater) before making landfall in Rhode Island as a Category 2 storm. While its peak winds reached 115 mph, its economic impact was magnified by its path through high-value, densely populated New England coastal communities.
The financial toll of the storm is a subject of varying estimates. Some records cite approximately US$1.5 billion in damage (1991 dollars), which equates to roughly US$3.5 billion in 2026. However, other analyses suggest the damage could have reached as high as US$3 billion in 1991 dollars, a figure that translates to about US$7.1 billion today. This high ranking—placing it as one of the costliest U.S. hurricanes at the time—was driven largely by cleanup costs, uninsured losses, and food claims rather than just structural destruction.
The storm also caused significant logistical and infrastructure disruptions. It left 2.1 million people without power and triggered a massive evacuation effort. In North Carolina, between 50,000 and 100,000 people fled the Outer Banks, while thousands more evacuated from Cape Cod and other coastal areas. These movements caused major traffic backups, including an 11-mile delay on the Sagamore Bridge. The event underscored the high cost of coastal living, where even moderate rainfall and wind can result in hundreds of millions of dollars in damage to local economies.
