Henri off the coast of Florida
Henri off the coast of Florida

Tropical Storm Henri was a moderate tropical storm that struck Florida during the 2003 Atlantic hurricane season. The eighth storm of the season, Henri formed from a tropical wave in the Gulf of Mexico on September 3. Moving generally to the east, it strengthened to peak winds of 60 mph (97 km/h) two days later. Henri weakened to a tropical depression before making landfall near Clearwater, Florida, dropping heavy rainfall with minor flooding damage. Henri degenerated into a remnant low on September 8 and persisted off the east coast of the United States for a few days before moving back ashore over North Carolina. The system brought heavy rainfall across parts of the Mid-Atlantic before dissipating on September 17. In Delaware and Pennsylvania heavy rainfall damaged hundreds of houses and businesses. The resulting floods in Delaware were described as a 1-in-500-year event. The total damage by Henri along its path amounted to $19.6 million, but no deaths were reported. (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].
