The Coast Guard Auxiliary will shoot a large parachute flare off Leadbetter Beach on Monday afternoon for training purposes.
The exercise is planned between 3:30 and 4:30 p.m.
Sgt. Riley Harwood with the Santa Barbara Police Department said the flare will be bright, and will take a few minutes to float down to the water.
Members of the public who observe the flare are advised not to call 9-1-1.
