1. Intensity and category are for time of landfall; hurricanes may have been stronger at other times.
3. Saffir-Simpson Hurricane scale: Cat. 1 = weak; Cat. 5 = devastating.
4. While a hurricane's category is determined by maximum sustained wind speed, its intensity is determined by barometric central pressure. As Katrina illustrates, the two do not have a direct one-to-one relationship.
