It will take two hours to prepare the ground after rain stops and the cut-off time for a rain-truncated 20-20 match is is 4.38pm. In case the match is washed out, there is a reserve day tomorrow.
"Days like these are uncontrollable. You've got to accept it and carry on. If it stops raining we can make decisions," said umpire Shaun George.
"There were quite a lot of puddles and surface water on the outfield," he added.
