They're sparing no expense at Northampton. The umpires, fielders and batters emerge - accompanied by some vertical flamethrowers which burn away most of Northamptonshire's remaining fuel reserves in order to shoot flames into the air.
Amy Jones and Danni Wyatt are opening up for England. Stand by for fires of the metaphorical king to be lit...
While we wait for the umpires... England bowler Kate Cross has been telling BBC Radio Manchester about three decisive moments on her cricketing journey.
You can hear the whole interview here.

The Fran Wilson catch the other day went viral on social media. That's the sort of thing some of these West Indies players are capable of - moments of individual brilliance.
Some people were saying she should be in the side just for her fielding!
In modern times, Wantage Road has hosted three women's ODIs (with England losing all three, to India in 1999, Australia in 2001 and New Zealand in 2004). But it's been a happier hunting ground in T20, with England winning all five games (four against South Africa, and one against West Indies) between 2008 and 2014.
What of Northampton, the ground which launched the careers of Graeme Swann and Monty Panesar, as well as media luminaries such as TMS's Alison Mitchell and Wisden editor Lawrence Booth?
Well, it was the first English ground ever to host a Women's Test back in 1937, which Australia won by 31 runs. Making her England debut that day was the remarkableEileen Ash(then known under her maiden name Eileen Whelan), who at 107 is the oldest surviving international cricketer in the world. You may remember Eileen ringing the Lord's bell at the 2017 Women's World Cup final, or putting current skipper Heather Knight to shame on the yoga mat, as she revealed in a column for BBC Sport.

Britney Cooper enjoys the T20 format, hopefully she's also feeling better from the other day.
Henry Moeran adds: She was a little ill on the outfield the other day. She took a great catch, chucked the ball up... then chucked something else up.

Some of the West Indies players have spoken openly about their lack of support [from the board]. The underlying infrastructure of women's cricket there is pretty bleak, only the top three or four players can make a living from cricket and there's no indication from the board that it will improve in the short term.
There's no visible plan, they've not backed a winning team after they won the World T20 in 2016.
I can't believe the time has flown by, but it's 10 years today since England won the inaugural Women's World Twenty20 at Lord's, bowling New Zealand out for 85 and chasing down the runs with three overs to spare. It meant they held the Ashes, World Cup and World T20 trophies simultaneously.
Sarah Taylor, Jenny Gunn, Katherine Brunt and Laura Marsh are still in the England squad from the XI on duty that day, while Beth Morgan is still turning out for Middlesex.
Of the Kiwi XI, Suzie Bates, Amy Satterthwaite and Sophie Devine are still regulars for the White Ferns, while Rachel Priest and Sara McGlashan are still playing in domestic leagues like the Big Bash.

The crowd in St Lucia at the World T20 really lifted that West Indies team. It wasn't quite the same in Antigua and we had some one-sided semi-finals.
But when the crowd lifts the team, the team plays at their best - not just from a skills point of view, but from an entertainment point of view. We didn't really see that in the one-day internationals.

West Indies are a very hot and cold side - the men's side are as well. I don't know if that's a deep-rooted problem in West Indies, or something they can address. When they're on a hot one, like they were in St Lucia, it's great to watch.
We don't have a set batting order for England, as they handed in the team sheet alphabetically, but we expect it could be something like:
Danni Wyatt, Amy Jones, Tammy Beaumont, Sarah Taylor (wk), Natalie Sciver, Heather Knight (capt), Katherine Brunt, Anya Shrubsole, Sophie Ecclestone, Kate Cross, Linsey Smith.
This is how we think West Indies will line up:
Hayley Matthews, Britney Cooper, Stafanie Taylor (capt), Chedean Nation, Kycia Knight (wk), Natasha McLean, Chinelle Henry, Stacy-Ann King, Afy Fletcher, Karishma Ramharack, Shamilia Connell.

West Indies knew they were going to lose all three ODIs within about 20 overs of the match starting. Without Deandra Dottin, if Stafanie Taylor and Hayley Matthews don't perform, there's no-one to guide the middle and lower order.
Look at the way England had Katherine Brunt, Anya Shrubsole and Sophie Ecclestone to smash sixes at the end of the innings. West Indies don't have anyone to do that.

England have been in good form in this T20 format, I think they've won most of their games and they have a great record since the World T20. They must know that West Indies are strongest in this format, I'd still back them to chase down something in excess of 140. But will West Indies still be scarred from the ODI series?

I think Australia arrive this weekend, they'll soon be up in Loughborough preparing for the Women's Ashes.
We've just heard about the England men's upset in Leeds today.

Test Match Special are up and running - so please point your wireless towards BBC Radio 5 Live Sports Extra, or click the "play" button at the top of this very page, to have a listen.
Henry Moeran, Natalie Germanos, Ebony Rainford-Brent and Isabelle Westbury are your top team on duty today.
The Windies make one change from the last ODI - with Chinelle Henryrecalled in place of Shemaine Campbelle.
England recall Katherine Brunt and Natalie Sciver who were rested for the final ODI, and also hand a place to spinner Linsey Smith who was brought in for the T20 leg of this series.
Out go Fran Wilson, Jenny Gunn and Bryony Smith - the latter was not selected for the T20s.
West Indies captain Stafanie Taylor says her hand is "a lot better" after she injured it in the field during the last ODI, which left her unable to bat in that game.
England win the toss and bat... teams as soon as I get them.
