The Long-Term Alert is used as an alternative to the (Short-Term) CAP Alert Banner. It should be used for less critical and longer-term alert messages. It can be displayed with or without the CAP Alert Banner.
It's content is composed with a Body Text component. The first line of text correlates with the left-most text before the callout-style list bullets. After this line of text, a standard bulleted list is expected, which is used to generate the callout-style list bullets.
In order to disable the Long-Term Alert message, it is recommended that the shared content page containing the alert configuration is unpublished. When a new alert should go out, an author can simply edit the alert contents and re-publish the shared content page.
