Because September marks National Preparedness Month, public safety officials are urging residents and businesses to prepare for the many hazards that threaten our daily lives and sense of normalcy – most often occurring in Southern California with little to no warning.

Whether it’s wildfires due to the state’s extended drought, mudslides, floods or massive earthquakes, disasters occur rapidly, forcing evacuations and road closures to neighborhoods.

AlertOC, the County’s mass notification system, is a critical link for residents to immediately learn of any required actions, such as evacuating their homes during an imminent fire.

On Thursday Sept. 22, more than two million Orange County residents will receive a call to test AlertOC.

The drill will replicate a large scale, multi-jurisdictional emergency requiring thousands of numbers to be called simultaneously across Orange County’s entire region.

This is the seventh annual regional test of the system and will include 26 participating cities as well as the County’s unincorporated areas.

The distinctive feature of AlertOC is the ability for individuals to register multiple contact methods and addresses.

Registrations of cell phone and alternate numbers dramatically increase the ability to reach the greatest number of community members within minutes.

This enables landlines, cell phones and e-mail addresses to be incorporated into a single notification system.

Residents can do their part to prepare for emergencies by registering for AlertOC.

The time is now to self-register cell phone numbers and e-mail addresses to be a part of the regional test.
