AlertOC Regional Test 2017

Several cities throughout Orange County are conducting a test of the County's emergency notification system AlertOC. Throughout the day October 18, 2017 residents may receive phone calls, text messages and emails from the AlertOC system. The purpose of these messages is to test AlertOC’s ability to deliver emergency notifications to county residents during a disaster. During an actual emergency, important information and instructions will be sent to you through AlertOC. We encourage all residents to register your cell phones, text devices and email addresses at to ensure that you receive emergency messages for incidents impacting your home, business, or school. Please share this information with your friends and family members living within Orange County and encourage them to sign up for these important alerts.
