An emergency siren that was part of the city’s siren warning system sounded in error at 8:03 this morning and was heard in various parts of the city. Despite the daily system-wide test that was conducted at 8 a.m. that showed all sirens to be functioning normally, one siren sounded in error when there was no emergency. Each of the 15 sirens in the city’s system are being thoroughly examined. The city apologizes for any inconvenience this may have caused.
