Napa County Sheriff’s Office debuts warning siren

Residents who hear the ‘hi-lo’, European-sounding law enforcement siren blaring from a Napa County sheriff’s vehicle should begin thinking about a wildfire or other possible danger.

On Monday, the Sheriff’s Office marked the first anniversary of the Atlas, Partrick and Tubbs fires by demonstrating new disaster communication tools. The sirens that alternate rapidly between high and low pitches—compared to the usual wail—are key.

Sheriff John Robertson explained how rural residents should react when they hear the hi-lo siren.

“It’s time to tune in,” he said. “It’s time to turn on your television, turn on your cell phone, to get those Nixle alerts as long as those towers are still up and functioning. Work with your neighbors. Communicate.”
