 Fortunately, that hurricane weakened before it made landfall as a Category 4 storm with 150-mile-an-hour winds. And do we know of great storms in earlier centuries, even if we don't have the instruments? You know, we do. There are a lot of records of hurricanes going back to colonial times. And in particular, there's a hurricane called the Great Hurricane, which occurred during the American Revolutionary War back in 1780.
