The outdoor warning sirens at Leilehua High School will be tested by the city Department of Emergency Management this afternoon.

Residents in the vicinity of Leilehua High School can expect to hear 20-second siren soundings during the testing, expected to run from about 1:30 to 2:30 p.m.

The test, being conducted in conjunction with Hawai'i State Civil Defense, is being done to ensure that the siren is operating at full power and providing optimal range.

State Civil Defense funds are used to purchase and install the city's sirens. Once installed, they are released to the city for monthly testing and emergency activation.
