...and they're going to stay on for now. TMS commentator Neil Manthorp is optimistic that the storm may have avoided Centurion.

Batsmen: De Kock 30, Amla 22

Bowling figures: Willey 3-0-17-0, Topley 4-0-24-0, Stokes 2-0-4-0, Jordan 1-0-11-0

England: 318-8 (50 overs) - Root 125, Hales 65, Stokes 53

Full scorecard

Amla guides another single off his legs, De Kock spears one to mid-off, it's 11 off the over and now the umpires are going to discuss the nearby lightning it seems...

"Oh my word. He is not the strongest batsman on either side by a long, long way, but the ball can leave his bat with greater speed than almost anyone else’s."

Chris Jordan didn't come on until well into the SA innings at Port Elizabeth, only coming on as the sixth bowler, but today he's being used with the 10-over fielding restrictions still in place. Amla steps across to the off side, well outside off stump and unleashes a fluent cover drive for four - that's the fifty stand. Jordan's riposte is an off-side wide which is well outside the tramlines, as though he anticipated Amla stepping across again. And as if to show his versatility, Amla *does* step across next ball - but deflects another wristy four through fine leg.

"They have worked really hard and are a quartet of great potential but the greatest power of strike is probably Stokes."

It's not quite time to batten down the hatches yet at Centurion, but if that lightning gets any closer, the fans gathered around their braais will be running for cover. A tighter over from Stokes, just an Amla single from it.

And although we can't have a game until 30 overs have been bowled, suffice to say SA are about seven runs ahead on Duckworth/Lewis at the moment.

"From an English perspective it is looking ominously easy for the South African’s to score their runs.

"And my goodness De Kock times the ball well."

Topley to continue, and after a legside wide, the two-paced nature of this pitch is shown as one rears up at De Kock and hits the splice of his bat as he fends it off. But unbowed, he helps a loose delivery to the fine leg fence for four... then a checked straight drive past the non-striker - in fact, Amla has to do the splits to let the ball through - takes De Kock to 28 from 28 balls. Two more singles, Topley has 0-24 from four and it's probably time for a change at his end.

And suddenly there's a flash of lightning and a roll of thunder... Messrs Duckworth and Lewis might need to strap the pads on after all.

"It feels like a play-on pitch, with the indifferent bounce. I would far rather be in England’s position with runs on the board."

An early, pro-active bowling change from Captain Morgan as Ben Stokes is into the attack with his brisk right-arm medium-fast seam. South Africa pick up a couple of singles, Stokes strays with a wide, and though they have runs on the board, I'm sure England fans will start to worry the longer this partnership goes on...

This is the run-out which Ebony and Simon were talking about on TMS. Definitely worth a watch.

Too wide from Topley, and De Kock helps himself to another four through the covers. 28 of these first 29 runs have come in boundaries... De Kock knocks a single to third man. The Proteas are on easystreet so far.

"Amla is like a magician when he is in full flow. He magics the ball through the infield with no effort. He has three hundreds here so England will want him out quickly.

"He is looking dangerous."

The boundaries continue to flow as Amla effortlessly drives a four past the despairing dive of Moeen Ali at mid-off. He remains a wonderful player to watch when he's in good nick, and now he helps himself to four more, this time a wristy flick off his legs. A good start; England were 31-0 at this stage but soon lost Jason Roy.

"No sign of swing for either of these left-armers. They swung it at Port Elizabeth but it is straight today."

While South Africa's tail has been slightly lengthened by the inclusion of all-rounder David Wiese at the expense of specialist batsman Rilee Rossouw, make no mistake, there's plenty of batting power in their line-up. And with the way De Kock was hitting them all around Bloemfontein before the rain came, an early wicket would not come amiss from England's perspective. The left-handed wicketkeeper takes aim at mid-on but an inside edge takes it for four through fine leg. There's an lbw appeal off the last ball - more from the keeper and slip than from the bowler - but it looked to be going down leg. "Wickets missing" says the ball-tracker.

De Kock, standing tall, chops the ball into the covers and some awkward bounce takes it away from Chris Jordan, but skipper Eoin Morgan cleans up to restrict the Proteas to a single, their only scoring shot from the over.

It's left-arm seam from both ends as the heavily tattooed Reece Topley bowls to Hashim Amla - whose pads seem a much brighter shade of green than those of his team-mates. And his strokeplay is as bright as the aforementioned pads as Amla square-drives for four. However, he gets a visit from the physio between overs to tape up his right hand.
