Two new emergency sirens around Oahu are being tested today.

Residents in affected neighborhoods may hear the sirens sound six to eight times over 30- to 60-second intervals. The testing will span from 9 a.m. to 3:30 p.m. and includes the following areas:

• Sand Island Access Road
• Hawaii Youth Correctional Facility

The new sirens are part of the Statewide Siren Modernization Project, the city Department of Emergency Management said. Two other sirens, one near Kahuku Shrimp Farms and another at Hawaii Youth Correctional Facility, were tested Wednesday.

In light of the recent siren malfunctions in Halawa, the department reminded residents that whenever the emergency siren system is activated for an actual emergency or a test “we will always disseminate information over TV, radio or official social media means to inform our residents during an emergency or prior to siren testing.”

Damaged or malfunctioning sirens can be reported to the department at 723-8960, or via email at dem@honolulu.gov.
