Katrina made landfall over the Florida Keys days before as a tropical storm.

Katrina's track from the Florida Keys to its New Orleans landfall is shown in this satellite photo blending several images with the track superimposed.
Katrina was a Category 5 shortly before landfall. It weakened to a strong Category 3 as it made landfall with at least 80% of the city experiencing Category 1 or 2 level sustained winds. New Orleans was hit with winds of 125 miles per hour. Below is a closeup high resolution satellite photo of the eye before landfall.
The eye over New Orleans
This graphic shows the level of the city compared to the level of the Gulf of Mexico. You can understand why 80% of the city was under water.
It proceeded inland with winds rapidly decreasing as shown below.
Hurricane Katrina's track headed north through Tennessee, Kentucky and Ohio as a depression with heavy rains.
The total rainfall from Katrina was incredible across the south. 8 to 10 inches of rain fell across the eastern half of the state with a local report of 15 inches near the Mississippi border. Amounts of 1 to 2 inches for us in Cleveland were common several days later.
The rainfall swath was similar to the rainfall areas created by the track of Hurricane Camille in 1969.
High winds were reported as far north as Detroit and Cleveland of over 50 miles per hour.
