The Hawaii Emergency Management Agency plans to test three sirens between 9 a.m. to 4 p.m. today on Oahu.

During that time, the sirens will sound intermittently. The sirens to be tested, according to HI-EMA, are at Kaneohe Beach Park, Waimanalo Beach Park and Mokapu Saddle Road. It is only a test.

All three sirens were installed as part of HI-EMA’s ongoing siren repair and upgrade program. Over the next few months, other sirens will be updated and additional sirens installed at various locations across the state.
