The Hawai‘i Emergency Management Agency monthly test of the statewide outdoor siren warning system, coordinated with the test of the live audio broadcast segment of the Emergency Alert System is scheduled for Tuesday, Jan. 3, 2017, at 11:45 a.m.

The siren test is a steady one-minute tone on all sirens. The steady tone is used to alert the public to any emergency that may pose a threat to life or property.

Besides natural hazards, the Emergency Alert System could be used for terrorist incidents or acts of war.

Contact your county civil defense/emergency management agency to report siren operation issues:

Hawai‘i Island (808) 935-0031
Maui (808) 270-7285
City and County of Honolulu (808) 723-8960
Kauai (808) 241-1800


Upon hearing a siren, residents are urged to tune to any local radio or television station for emergency information and instructions. Participating stations will carry a detailed explanation of what the sirens mean, as well as other related information.
