In a widespread, actual emergency, provided that you can safely shelter at home and can maintain emergency power and communications, you can become a source of information for emergency preparedeness agencies regarding conditions and needs in your immediate area. If you would be at a shelter anyhow, you can be a communicator from that location. Contact your local ARES/RACES group and let them know that you are interested and what your capabilities are.
