Newport Beach will test its emergency notification system this morning by placing automated phone calls to residences and businesses citywide.
More than 110,000 people are scheduled to receive notification of the test via telephone between 10 a.m. and noon.
The annual test comes a few months after the AlertOC, which operates in 32 Orange County cities, failed when attempting to alert county residents of a tsunami advisory in late February.
Costa Mesa and Irvine are not part of the AlertOC system.
Residents and business owners will receive a short, automated phone call to their landline or other designated contact, such as a cell phone or e-mail, which they have voluntarily registered with AlertOC.
