To register your phone to receive Emergency notifications updates visit: http://jeffco.us/sheriff/code-red-emergency-notifications/
UPDATE:
The number that was posted referring people to set up the CodeRED alerts has been removed due to the fact that the system was being overloaded. We are asked to now refer people to http://your911.net.
Also: If the address of your phone is not in Broomfield or Jefferson Counties, you will not be able to register.
