Although vulnerability and potential loss results have not been prepared for tropical cyclone, the following keysubhazards caused by tropical cyclone are included: flooding and severe wind. In addition, a quantitative vulnerability analysis has not been prepared for HAZMAT sewage discharge because the sewage is discharged directly into the ocean and therefore does not affect the assets and population onland.5-61
