Entergy will conduct a test of all Indian Point sirens in Westchester, Rockland, Putnam and Orange counties on Wednesday, Aug. 15, beginning at 10:30 a.m. All the sirens will be sounded for four minutes at full volume followed by an activation of the Emergency Alert System on radio and television stations. This is only a test. No response on the part of the public is necessary.
In an actual emergency, the sirens would sound continuously at full volume for four minutes, followed by the broadcast of an Emergency Alert System (EAS) message on radio and television stations. Sirens are not a signal to evacuate, but rather for people to tune to an EAS radio or TV station for information and instructions.
