Camille in the Gulf of Mexico
Camille in the Gulf of Mexico

Hurricane Camille was the third named storm of the 1969 Atlantic hurricane season. It formed as a tropical depression on August 14 south of Cuba; it strengthened and struck western Cuba the next day as a hurricane, killing at least five people. Camille strengthened into a Category 5 hurricane in the Gulf of Mexico on August 16 and two days later moved ashore in Mississippi, attaining maximum sustained winds of 175 mph (282 km/h) and a minimum pressure of 900 mb (27 inHg). Camille killed at least 343 people in the US and caused $1.42 billion in damages, making it the country's most expensive hurricane at the time. In southern Mississippi, the hurricane produced the largest storm surge in American history at the time, with a peak water level of 24.6 ft (7.5 m). The highest rainfall total was 27 in (69 cm), recorded in Virginia, and was the highest rainfall recorded in the state related to a tropical cyclone. The name Camille was retired following the 1969 hurricane season. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
