And the following criteria:

(a) The final category can never be lower than the highest hazard-based category;

(b) The TCSS should adequately reflect the case of high potential risk of two or more hazards. We consider a hazard of high risk when its respect- ive category is classified as 3 or higher (equal to the definition for a Major Hurricane on the SSHWS). Whenever (at least) two high risk haz- ards have the same category value and the third hazard has a lower category value, the final category should increment the highest hazard- based category. This implies that a TC scoring a Category 3 on both wind and storm surge, and a Category 1 on rainfall, will be classified as a Category 4.

(c) To warn the general public for an event with multiple extreme hazards, a high-risk TC can be classified as a Category 6 when either 1. at least two of the hazard-based categories are of Cat- egory 5; or 2. two categories are of Category 4, and one of Category 5.
