Rides close and reopen again all of the time, and it can be for a plethora of reasons, which are hardly ever officially explained.
It could be high winds, up at 236ft; it could be a customer has evacuated themselves; it could be that the swans are back and having a splash in the trough. There's also a difference in the ride being closed, and the queue for the ride being closed. If the queue for the ride is closed, but hasn't been evacuated, then it's expected that the pause in operation will be short and temporary. If the queue has been evacuated, then something requires more attention and it could take a while longer to reopen.
Given that the park is open until 9pm, I would expect it to reopen.
