HONOLULU (HawaiiNewsNow) - Some Oahu residents will hear the emergency sirens outside of the usual, first of the month tests, Wednesday and Thursday.
The Hawaii Emergency Management Agency, or Hawaii-EMA, installed four new emergency sirens. The agency says they will test them on Jan. 18 and 19.
The Kahuku Shrimp Farms and Haleiwa Beach Park sirens will be tested on Wednesday while the Sand Island Access Road and Hawaii Youth Correctional Facility sirens will be tested on Thursday.
The sirens will sound anytime between 9 a.m. and 3:30 p.m on both days.
The state is working on updating the siren system statewide.
On Tuesday, residents in Halawa woke to the sound of a runaway siren just after midnight, although there was no emergency.
Officials do not know what caused the siren to malfunction.
In the first week of January, sirens were triggered inadvertently just hours before the monthly test. In this case, Hawaii-EMA says a Honolulu police dispatcher accidentally pressed a button that triggered the alarm around 8 a.m.
