Poor weather has disrupted the French Open at Roland Garros for a second day.
Tournament organisers were already facing a backlog of matches after only four hours of play were possible on Sunday because of rain.
And the wet conditions delayed Monday's start time of 10:00 BST, with play not expected to resume until the afternoon.
British number two Heather Watson is waiting to resume her round one match, poised at one set all, with American Nicole Gibbs.
British number one Andy Murray is scheduled to face 37-year-old Czech Radek Stepanek in the fourth game on Philippe-Chatrier Court, but it is now likely they will play on Tuesday, along with world number ones Serena Williams and Novak Djokovic.
