Instead, letâs express these unique differences as a vector: 1  The size of the cross product is the numeric âamount of differenceâ (with sin(theta) as the percentage) 2  The direction of the cross product is based on both inputs: itâs the direction orthogonal to both (i.e., favoring neither)
Main Content. Hurricane Katrina was a long-lived hurricane that made landfall three times along the United States coast and reached Category 5 at its peak intensity. The storm initially developed as a tropical depression in the southeastern Bahamas on August 23, 2005. Two days later, it strengthened into a Category 1 hurricane a few hours before making its first landfall between Hallandale Beach and North Miami Beach, Florida.
Hurricane Katrina affected over 15 million people in different ways varying from having to evacuate their homes, rising gas prices, and the economy suffering. An estimated 80% of New Orleans was under water, up to 20 ft deep in places. Hurricane Katrina caused $81 billion in property damages, but it is estimated that the total economic impact in Louisiana and Mississippi may exceed $150 billion, earning the title of costliest hurricane ever in US history. Hurricane Katrina impacted about 90,000 square miles.
