Hawaii’s nuclear warning system was barely audile at Waikiki Beach in Hawaii during their test on Saturday. The siren is designed to give people 20 minutes notice to take shelter in case of a nuclear attack.
Officials are now checking the system to figure out if it needs repairs or just needed to be turned up to be better heard. Hawaii is the first state to bring back the Cold War era sirens, saying that they want people to be prepared in the remote possibility of a strike. (source) 4:17 p.m. ET December 2, 2017
