Hilary near peak intensity off Mexico
Hilary near peak intensity off Mexico

Hurricane Hilary was a large and intense Pacific hurricane in August 2023 that brought torrential rainfall to the Pacific Coast of Mexico and the Southwestern United States, resulting in widespread flooding. It was the eighth named storm, sixth hurricane, and fourth major hurricane of the active and highly destructive 2023 Pacific hurricane season. Hilary originated from a tropical wave south of Mexico on August 16, and became a hurricane a day later. It underwent rapid intensification, reaching maximum sustained winds of 140 mph (220 km/h) on August 18, making it a Category 4 storm on the Saffir–Simpson scale. Thousands of people evacuated to shelters as ports closed along the Pacific Coast of Mexico. In anticipation of "catastrophic and life-threatening flooding", the National Hurricane Center issued its first-ever tropical storm warning for Southern California, extending from the Mexico–U.S. border to just north of Los Angeles. Death Valley National Park closed for two months. (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].
