There were signs that the rain over Johannesburg might be clearing two hours before the start of the Standard Bank Pro20 match between South Africa and the West Indies at the Wanderers on Friday.
Steady rain fell over the city for much of the day, but spectators were already trickling into the ground.
The West Indies have a one-nil lead in the two match series, having beaten the Proteas by five wickets in the rain-affected match in Port Elizabeth last month.
