Monitoring relevant tweets is recommended if your ongoing alarms are based on events of this kind (e.g. natural disaster, terrorist attacks, bomb threats etc.). This will keep you up to date with developments and enable you to take appropriate action where necessary by sending interim status reports, all-clear reports etc.
