Lancashire Lightning and Glamorgan saw their NatWest T20 Blast quarter-final washed out without a ball bowled at Emirates Old Trafford, raising the prospect of a second bowl out in five years for the hosts.
Lancashire's last-eight tie against Somerset at the same venue in 2009 was washed out on four successive days before the visitors won cricket's version of a penalty shootout 5-1 to advance to Finals Day.
There is now a reserve day on Saturday, with the clash due to start at 2pm and the cut off for a start at 8.57pm.
If the weather forecasters are correct and the rain continues to fall, a decision will be taken between the two counties and the England and Wales Cricket Board as to whether there is a bowl out on Saturday or they move it into a second reserve day on Sunday.
Emirates Old Trafford hosts the fourth Investec Test match between England and India, starting on Thursday.
Play today has been abandoned and we will try again tomorrow at 2pm. Tickets for today are valid for tomorrow

Of the chances of the match going into Sunday, umpire Peter Hartley said: "It is not set in concrete, there is still room for negotiation. But the club (Lancashire) would like to get it finished on Saturday.
"There are certain regulations about playing on the ground so close to the Test match beginning."
Lancashire cricket director Mike Watkinson added: "The ECB have been pretty flexible. We're doing everything we can to get the game through tomorrow, and they've given us a big window, looking to start at 2pm with a normal cut-off at 9.45pm.
"We've got as big a chance as possible to get the game done tomorrow, which we want.
"We've got a Test match here starting on Thursday, and the quality of the playing surface for that is crucial for us. We think we've got a good pitch out there. We're obviously mindful of protecting that.
"If we can avoid playing on Sunday, that would be fantastic.
"I think we've tried to shut Sunday off as an option, but because of the flexibility of the rules, if people start screaming tomorrow 'look at the great forecast for Sunday', maybe there is an opportunity to look at that again.
"As it stands we're on get it in tomorrow or bowl out tomorrow evening."
