The start of the second Ashes Test has been delayed because of rain, with further showers forecast on what shapes to be an anticlimactic opening day at Lord's.
The toss was slated for 7.30pm AEST but is now set to take place at midnight AEST.
It is possible the entire day's play will be washed out but umpires, having conducted multiple pitch inspections and worried about a damp outfield, are confident of squeezing some play in on Wednesday.
The pitch was blanketed with heavy covers throughout what should have been the morning session, during which the most encouraging sign was groundsmen sweeping water off them.
The showers eventually stopped and the covers came off as umpires scheduled their first pitch inspection for 11pm AEST.
The peeling back of the covers prompted coaches Justin Langer and Trevor Bayliss to rush out and have a close look at how the deck coped with the downpour.
The iconic venue is renowned for its efficient drainage, a combination of the 2.5-metre slope and work on the outfield completed in 2002.
Australia hold a 1-0 lead in the five-Test series, having won by 251 runs at Edgbaston thanks largely to two centuries from Steve Smith.
James Pattinson has been rested from the clash in London but the tourists are yet to confirm whether Josh Hazlewood or Mitchell Starc will claim his place in the XI.
England captain Joe Root is also yet to announce his team, with the hosts weighing up whether to leave left-arm spinner Jack Leach on the sidelines and bank on an all-pace attack.
Root suggested the prospect of losing a day to wet weather wouldn't influence England's selectors.
"You've got to keep an open mind and Test cricket is all about adapting anyway," Root said in his pre-match press conference.
"I'm sure that if the weather throws up some surprises or has a big say in things, we'll have to make sure we manage that well."
