Hi-Lo Siren

This European Siren produces an "unfamiliar sound", however it has a major role in alerting the public of emergencies.  When you hear this siren, seek media news (television, radio, reliable social media news sources) immediately.  This plan was developed by Napa County Sheriff, John Robertson. So far, Sonoma, Solano and Lake County Sheriff's Offices have joined Sheriff Robertson by implementing the Hi-Lo Siren since October 9th, 2018, the first anniversary of the 2017 wildfires.
