If you hear the sirens for a few seconds today, Friday, Jan. 25 and on Monday, Jan. 28, it's the three-month "growl test" of the community alert siren system conducted by San Onofre Nuclear Generating Station (SONGS).
The nuclear plant tests its community alert siren system every three months. There are nine sirens in San Juan Capistrano. Each one is tested individually for a few seconds, which is known as a "growl" test.
This test is different from the annual test in October, which calls for sounding off all sirens at the same time for a 3-minute duration. In an actual emergency, the sounding of the sirens means residents should turn on their radios/televisions for instructions to find out what course of action is required.
