SAN LUIS OBISPO, Calif. (AP) — Officials say a series of erroneous emergency alerts was issued in San Luis Obispo county amid repairs to a nuclear power plant's siren system.
County emergency services manager Ron Alsop says that on Friday afternoon, a siren for emergencies at the Diablo Canyon nuclear plant began wailing for no apparent reason.
Earlier in the day, crews had upgraded the siren as part of a revamp of the emergency system by Pacific Gas and Electric Company.
County officials issued an alert message indicating there was no emergency, but the alert unknowingly triggered a text message warning that there was a "civil emergency" in the area and that people should "prepare for action."
Officials tried to clear up the confusion by sending out a final message stating that there was no emergency.
