flashing

The video, taken less than a mile from the suspected ignition point of the fire, shows the strong winds whipping through the area, and in the distance light flashing on the dark hillside.

One resident, Mike Ainscough, said people would continue to "tremble" with worry at the sight of blue flashing lights.

To recap: Pretending it was a "joke," white nationalists, starting around 2015, started flashing the OK hand gesture as a sign of racist solidarity.

In a properly installed system, people are then directed by announcement to the nearest fire exits, with flashing lights for people who are hearing-impaired or audible warnings for those sleeping.

“In my 35 years in the fire service, I have never heard the weather service use those words. It was a flashing danger sign.”
