Throughout its course, the storm went through several phases of severity.Continue Reading
Katrina began as mere storms in the Bahamas before developing into a tropical depression. By the time it reached the coast of South Florida, it was classified as a tropical storm. While traveling across Florida, it evolved into a low-category hurricane. Over the Gulf of Mexico, the storm reached its most intense levels as it graduated from a category-3 to a category-5 hurricane. By the time it reached the coast of Louisiana, it had been downgraded to a strong category 3.
A category-5 hurricane is the most intense hurricane on the Saffir-Simpson Hurricane Wind Scale, which is used to determine the severity of hurricanes. At category 5, hurricane winds can be in excess of 155 mph and catastrophic damage is a virtual certainty. Even a category-3 hurricane can produce winds of up to 129 mph. This is why southern Louisiana and Mississippi incurred so much damage as a result of Hurricane Katrina. Hurricane Katrina remained a category 3 as it traveled over Louisiana and parts of Mississippi. It did not downgrade to a tropical storm until it reached the northern half of Mississippi.Learn more about US History
