Yes, Slinky Dog Dash at Disney's Hollywood Studios will close during heavy rain or if there is lightning detected within a 10-mile radius. As an outdoor roller coaster with a steel track and sensitive electronic launch systems, the ride must suspend operations for the safety of both guests and the machinery. In 2026, Disney utilizes advanced "MinuteCast" weather tracking to provide guests with real-time updates via the My Disney Experience app. If the rain is light and there is no electrical activity, the ride may remain operational, but guests will likely experience a "sting" from raindrops hitting their faces at high speeds. Once a lightning delay is called, the ride usually remains closed for at least 30 minutes after the last strike. If you are in the queue when it closes, you are typically given a "Multi-Experience" Lightning Lane pass for later use.
