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 was the eleventh named storm and fifth hurricane of the 2005 Atlantic hurricane season. It was the costliest natural disaster, as well as one of the five deadliest hurricanes, in the history of the United States. The storm is currently ranked as the third most intense United States landfalling tropical cyclone, behind only the 1935 Labor Day hurricane and Hurricane Camille in 1969.
