HONOLULU (AP) -- Hawaii is reinstating the system intended to warn people of an impending nuclear strike just days after North Korea launched its most powerful missile yet.
The state on Friday will test a new tone for an attack in its siren warning system. The wailing sound of the attack warning will come after the long, steady siren for tsunamis and other natural disasters.
The governor says the test will ensure the public knows what they should do in case of an imminent attack. Officials say if a missile is launched, people would have less than 20 minutes to take shelter.
But some residents and visitors have expressed confusion about what they were supposed to do after hearing the siren.
