I was on CIC (Controller in Charge). Helicopters were in bound to the field from the northwest; expected to join a VFR arrival route. Weather wasn't good. Poor visibility and wind shear to the west. The trainee had given traffic on the inbound helicopters to Aircraft X about 10 miles out. The helicopters appeared to be south of course to avoid clouds and Aircraft X got a CA (Conflict Alert) about 5 miles from the runway. I asked the trainee if he had updated the traffic to get him to look; either out the window or at his screen at the traffic. The trainee said he already gave the traffic and it wasn't an issue. Aircraft X continued to have the CA all the way into the runway. We've had issues with helicopters; which are mostly seasonal; all summer long. The VFR arrival/departure is way too close to final for Runway 8. On weather days; they are very hard to see. These helicopter companies have been flying in flights with paying passengers all season as well. We have multiple aircraft inbound to Juneau from that area. This is not safe. The trainee should pay attention since this was very slow traffic and update traffic calls. Aircraft X had a CA with multiple helicopters inbound to the field. This 'I don't care enough to look attitude' is what's going to hurt someone someday. Helicopters with paying passengers should not be flying in flights. We need to update the helicopter arrivals/departures into Juneau Airport.
JNU Tower Controller in Charge reported Local Control was not issuing sufficient traffic information about helicopters on a VFR route to an air carrier on final approach.
