It happened around noon on The Talon roller coaster.
Riders were on the lift tow approaching a downward hill when a warning light came on and the conductor decided to stop the ride.
Because of the rainy weather park officials decided to evacuate the ride instead of trying to figure out if it was just a false signal.
The passengers had to walk down the side of the ride.
There were no injuries.
Action News viewer Patrick Brown had his camera going and sent us video of the evacuation in progress:
