One CAP message, one visual language: from a social post to the full alert on the phone.
An alerting authority would publish the post on its own account. The post is drawn from the CAP fields of a live official alert, in the languages the authority sent. Tap the link, not the picture: platforms do not make pictures clickable.
Formats sized for these platforms. Not affiliated with or endorsed by them.
Cancelled and Expired are drawn from this live alert to show the template. They are not real messages and are labelled on the image.
A video post for a separate signed-alerts account, on every platform here (feed videos play muted, which sign language does not need): a signer panel plays one clip per fixed CAP code (warning level, hazard, action). The free text is never signed. Clips must be recorded by deaf signers in each national sign language PLANNED
