A hurricane with maximum sustained winds of 120 mph would be a category 3.
When Katrina's center was closest to New Orleans the storm had sustained winds of 120 mph,making it a category 3 hurricane.
No. Not even close. There are two main measures of hurricane intensity: wind speed and barometric pressure. Hurricane Irene is already past its peak of 120 mph winds and a pressure of 942 millibars (the lower the pressure, the stronger the storm). The strongest Hurricane on record in terms of wind speed was Hurricane Camille at 190 mph. The most intense tropical cyclone (generic term for hurricane, typhoon etc.) on recordwas Typhoon Tip with a pressure of 870 millibars.
Hurricane Katrina made three landfalls. At the first landfall in Florida Katrina had sustained winds of 80 mph. At the two landfalls in Louisiana and Mississippi Katrina was a category 3 hurricane with sustained winds of 125 mph and 120 mph respectively.
It varies. Irene was a high end category 2 with a pressure of around 942, but often that pressure would give you a a little bit stronger of a hurricane (maybe 120-130mph).
A hurricane with sustained winds of 122 mph would be a category 3.
120 mph (195 km/h) at the highest speed

Such a wind is considered hurricane force. However it is only a hurricane if such winds are produced by a tropical cyclone.
Sustained winds of 74 MPH or faster.

There are no measurements for Hurricane Jeanne, which hit Florida and the Caribbean in 2004. There were wind speeds of up to 120 mph.
Hurricane Katrina made three landfalls. At the first landfall in Florida Katrina had sustained winds of 80 mph. At the two landfalls in Louisiana and Mississippi Katrina was a category 3 hurricane with sustained winds of 125 mph and 120 mph respectively.

A hurricane with sustained winds of 122 mph would be a category 3.
A tropical storm with winds of 120 km/h (75 mph) or greater is called a hurricane.
The intensity rating of a hurricane is determined based on the maximum sustained wind speed of the storm. For example, Sustained winds of 120 mph will earn a storm a category 3 rating. Intensity can also be assessed based on the barometric pressure at the center of the storm. Lower pressure means a stronger storm. Rankings of intensity are based on pressure, as it is given as an exact figure, while wind speed is rounded to the nearest 5 mph. The size of a storm is based on the diameter of the area over which the hurricane produces sustained gale-force winds; winds of at least 35 mph.
There have been numerous Hurricane Irenes in history because the name cycles every 6 years and has not yet been retired. Most recently, Hurricane Irene in 2005 topped out at 105 mph. So far the Hurricane Irene that is currently active peaked at 100 mph before weakening to 90 mph. Currently the storm is expected to reach a second peak of 125 mph later this week.
