Early warning of an approaching cyclone is possible with enough time for individuals and communities to take protective measures, typically beginning as an alert 36 to 72 hours prior to landfall. For persons who need additional time or assistance to evacuate, early evacuation may be desirable, however, self-determination must be respected, and this includes the decision of persons with disabilities and older persons to shelter-in-place or evacuate.
To ensure weather surveillance information and early warning messages for cyclone reach and are understood by everyone in the community, use a combination of different audio and visual mechanisms for warning dissemination.
Particular attention should be paid to accessibility of early warning systems for underrepresented and invisible groups such as persons with hearing impairments and persons with intellectual disabilities.
