Receiving timely information about weather conditions or other emergency events can make all the difference
in knowing when to take action to be safe. Local police and fire departments, emergency managers, the National
Weather Service (NWS), the Federal Emergency Management Agency (FEMA), the Federal Communications
Commission (FCC), the National Oceanic and Atmospheric Administration (NOAA), and private industry are
working together to make sure you can receive alerts and warnings quickly through several different technologies
no matter where you are–at home, at school, at work, or in the community.
For those with access and functional needs, many messages are TTY/TDD compatible and many devices have
accessible accommodations. Review this fact sheet to make sure you will receive critical information as soon as
possible so you can take action to be safe. Be sure to share this information with your family, friends, and colleagues.
And remember to keep extra batteries for your mobile phone or radio in a safe place or consider purchasing other
back-up power supplies such as a car, solar-powered, or hand crank charger.
