5.10pm: Match abandoned, the rain is sticking to Kennington like cheap cologne and time has run out. But there is still every prospect of the weather clearing through in time for a full 100b men's game, starting in just under two hours. Feel free to tootle off in between times, we'll have comms up and running around 6pm or so. Bye!
5.01pm: The rain has just got heavier, according to Paul. Could well mean the plug being pulled on this one, sadly.
4.58pm: Well, figure this out - if there's no further rain, the aim is for a 30-balls game from 5.30pm. But. It's currently raining. Cricket, eh. Should never try meeting new people.
Alex Thomas isn't amused, from the sounds of it: "I've been at the ground since 3pm and apart from a five minute spell it's been completely dry! Get the game on!"
4.50pm: Rain again and more covers coming on, further frustration for the women at The Oval. The umpires are out there, having a chat with the two captains, but this looks like another delay in the offing
4.40pm: There'll be another inspection in 10 minutes' time. Paul Muchmore has this: "Seems to be a bit of a hokey cokey with the covers - taking some off, bringing some on. Sun's back out, players having a kickaround, umpires meandering around the middle." Reckon we might get some sort of game here.
"Any possibilities of playing the men's full match today??" wonders Fayaz. "Please let me know? If it's not playing I can go to bed very early since I have an important work tomorrow morning. Anyway I'm from Sri Lanka." But how old are you, Fayaz? And do you count as a #newaudience member? As for the men's game, yes, the forecast is decent and they have their own, separate window - so won't be affected by this delay
4.25pm: Raining again, "brollies going up, covers coming back on"... in short, exactly what we didn't want. Apparently 5.43pm is the cut-off for a 25-balls-a-side thrash, with the men's game scheduled for 7pm come what may. Anyway, go make yourself a cup of char, we'll keep you abreast of any updates.
4.15pm: The umpires are heading out for a look now - apparently there's a section of the ground at the Vauxhall End that is cause for concern. "Super sopper going back and forth at that point," says ESPNcricinfo's social media guru Paul Muchmore. Fingers crossed for more positive news shortly... although there does appear to be another band of rain hoving into view on the radar.
3.45pm: There'll be an inspection at 4.15pm, Matt's optimism was misplaced. So that will mean a reduced game - although the news is worse from the Midlands, where they have abandoned play on day five at Trent Bridge, meaning the first Test of the series ends in a draw.
3.40pm: An update from Matt: "bright sunshine now, clean-up in process, decent chance we get on before 4pm, which would mean no balls lost." As Matt points out, this game also features a sororital grudge match between Scottish siblings Kathryn and Sarah Bryce. Here's his piece on the pair from earlier in the summer.
3.25pm: Oh dear, some bad news on the weather front - it currently appears to be tipping down at T'Oval. "Torrential," says Matt Roller. The groundstaff have sprung quickly into action and the square is currently under full covers. Fingers crossed it will blow through soon.
3.20pm: Right, this should be tasty Sunday afternoon fare. Rockets are a team in form, winning three on the bounce after a slow start - and runs on the board have been a factor in two of those games, with the top three of Rachel Priest, Sammy Jo-Johnson and Nat Sciver beginning to hit their straps in the tournament. Invincibles have been a little more up and down since that dramatic win on opening night, in particular hampered by injuries. But van Niekerk is in sparkling form and they have the comp's second-leading wicket-taker in Tash Farrant (behind only Johnson), as well as the fiery Ismail back to lead the line with the ball.
3.05pm: Rockets win the toss and bat, Nat Sciver isn't too worried about the weather that's been around. "Our strength is to bat first, get a good total on the board and put pressure on with the ball," she says. Lucy Higham returns to the Rockets XI, with Nancy Harman sitting out. Dane van Niekerk wanted to bowl anyway, so both teams are happy. Shabnim Ismail is back for Invincibles, but Marizanne Kapp remains "touch and go", could be fit for the final couple of group games. "It was a good day out," says van Niekerk of victory in their last game at Edgbaston, "but we know how good Trent Rockets are, we'll have to bring our A game and hopefully it'll be a good show."
Oval Invincibles: 1 Dane van Niekerk (capt), 2 Georgia Adams, 3 Fran Wilson, 4 Alice Capsey, 5 Mady Villiers, 6 Tash Farrant, 7 Grace Gibbs, 8 Joanne Gardner, 9 Sarah Bryce (wk), 10 Shadnim Ismail, 11 Danielle Gregory
Trent Rockets: 1 Rachel Priest (wk), 2 Sammy-Jo Johnson, 3 Nat Sciver (capt), 4 Katherine Brunt, 5 Heather Graham, 6 Sarah Glenn, 7 Emily Windsor, 8 Abi Freeborn, 9 Kathryn Bryce, 10 Lucy Higham, 11 Georgia Davis
2.45pm: Hello hello. It's a day ending in y, so that must make it a Hundred double-header day! Come on in, it'll be tons of fun. The Oval is the scene for today's action - and never mind the issues with the weather around Nottingham, it's looking fine and dry down south. And this could be a vital encounter in the race for a top-three spot in the women's competition: Oval Invincibles and Trent Rockets are level on six points, with only two teams above them. Victory would send one of them up to second, above Northern Superchargers, and probably a win away from guaranteeing progression. Both teams come into this match in winning form, too. We'll have toss and team news for you shortly
