The Hawaii Emergency Management will conduct siren testing Wednesday in Waianae and Sand Island.

The sirens will be sounded in Waianae Shopping Mall from 9 a.m.- 11 a.m. and Sand Island Park from 1 p.m.- 3 p.m.

Residents in these areas may hear the siren sound for six to eight times during 30-second to one-minute intervals during the identified timeframe. Testing will include checks of the public address system and short blasts known as "burps." During the tests, technicians will check that recent work on the sirens have been properly completed, said the Hawaii Emergency Management Agency.
