This template contains icon overrides for Module:Storm categories. These icon overrides can either add an extra icon to the template without adding a category, or override the icon of an existing category or category alias for backwards compatibility. These are primarily used for categories that apply to basins across both hemispheres, but require an icon that applies to the southern hemisphere (where cyclones rotate counter-clockwise).

Overrides are defined in the following format:

    -- For overrides that include the icon of an existing category.
    ["override_id"] = cats["actual_category"].icon,
    -- For overrides that introduce a new icon.
    ["override_id"] = "[[File:Super duper ultra strong magnitude 100 storm icon.svg|18px]]",
