The Indian Point Energy Center will conduct a four minute full volume test of the alert and notification sirens on Wednesday, May 11 at 10:30a. The Rockland County Dept of Fire and Emergency Services writes,

A full volume test of the alert and notification sirens located throughout the emergency planning zone will be held Wednesday, May 11th at approximately 10:30 a.m. The sirens will sound for four minutes.

Please do not hesitate to contact the Office of Fire & Emergency Services at 1-800-942-1450, should you have any questions.

In the event of an actual emergency, the four minute sirens don’t signal an evacuation but are a prompt to tune to WHUD 100.7 FM for important information.

A new system, installed in 2009, includes 172 sirens covering the ten mile emergency planning zone around Indian Point.

To get an idea of what the siren test sounds like, there are several YouTube videos of past tests and how people respond to the sirens.
