Joaquin at peak intensity near the Bahamas
Joaquin at peak intensity near the Bahamas

Hurricane Joaquin was a powerful tropical cyclone in 2015 and one of the strongest hurricanes on record to affect the Bahamas. It evolved from a non-tropical low to a tropical depression, becoming a Category 4 major hurricane on the Saffir–Simpson scale on October 1. On October 3, Joaquin acquired sustained winds of 155 mph (250 km/h). Between October 1 and 3, it caused extensive damage on Acklins, Crooked Island, Long Island, Rum Cay, and San Salvador Island. Prolonged, intense winds brought down trees and power lines, and unroofed homes. Flooding persisted for days after the hurricane's departure. Relief efforts were hampered by heavy damage to airstrips and flooded roads. The Turks and Caicos Islands, Cuba, and Haiti were all severely affected. Over the Southeastern United States, a separate storm system drew tremendous moisture from the hurricane, leading to catastrophic flooding in South Carolina. Over its lifetime, Joaquin killed 34 people and caused US$120 million in damage. (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].
