If you hear explosions and gunfire at Arroyo Grande High, here’s what’s happening

If you hear loud explosions or gunshots at Arroyo Grande High School this week, don’t be alarmed.

It’s part of a training simulation.

The Arroyo Grande Police Department is hosting this year’s regional active shooter training at Arroyo Grande High School on Tuesday and Saturday, according to a news release. The training will run from approximately 8 a.m.-5 p.m. both days.

The training will bring a large law enforcement presence to the high school and could include the sound of simulated explosions and gunfire.

Some locations on the campus will be blocked off with caution tape, identifying areas being used in the training. Safety officers will be dressed in red training shirts, and officers participating in the drill will be in police uniform, the release said.

For more information on the training, contact the Arroyo Grande Police Department at 805-473-5100.

Also on Tuesday, PG&E will be holding a “Public Safety Power Shutoff” drill in the area, the Police Department said. Helicopters may be visible as part of that training.

And on Tuesday and Wednesday, the county Office of Emergency Services will be testing early-warning system sirens in the Diablo Canyon Emergency Planning Zone.
