@NorthantsCCC on Twitter: The rain keeps going and coming back again! frustrating for all involved.

@EssexCricket on Twitter: The toss has been delayed at The Essex County Ground. We are currently awaiting more information from our on field umpires.
6:42pm - No sign of play at New Road, I'm afraid, but at Headingley the game continues to move at a quick pace. Yorkshire have lost both Richard Pyrah and Liam Plunkett, leaving the home side reeling at 85 for seven. Madsen's decision to bowl first appears to have been the correct one!
With one over to go at the Emirates Durham ICG, Lancashire are 159 for two.
6:33pm - Simon Katich looks in the mood this evening, which is bad news for Durham. The Australian left-hander has crunched 37 from 16 balls, with two fours and three sixes, to give Lancashire some late-innings impetus.
The Foxes have suffered a setback, losing Josh Cobb for 21 from 10 balls.
6:24pm - Derbyshire have their fifth wicket! Wayne Madsen's men are really turning the screw with Mark Footitt picking up his second scalp. Adil Rashid can only muster four before he heads back to the changing rooms.
Leicestershire's innings is up and running, with Niall O'Brien sending an early Ajmal Shahzad delivery across the boundary rope.
6:15pm - Things go from bad to worse for the Vikings, who have now lost the key wicket of Bairstow. A mis-timed pull is caught by Groenewald as Derbyshire continue their impressive start to the encounter at Headingley. Yorkshire are 42 for four from eight overs.
Moore has a fifty from 40 balls for Lancashire, but he will have to make do without partner Steven Croft, who was bowled by Pringle.
6:10pm - It seemed too good to be true, and so it proved. Prince makes 32 before succumbing to Ryan Pringle and Durham are in the game. In the 11th over, the Lightning are 77 for one.
Ballance has made a slow start, accruing just two runs from his first 10 balls, as Yorkshire seek to rebuild.
@leicsccc on Twitter: Notts have won the toss and will field first
6:05pm - Yorkshire have an uphill struggle ahead of them now after Hodgson is run out by a direct hit from Dan Redfern. Solace arrives in the shape of Gary Ballance who, with Bairstow, still poses a serious threat to Derbyshire.
No such concerns for Lancashire who still have openers Moore and Prince at the crease. They are continuing to build a more-than-useful platform for the visitors.
@GlamCricket on Twitter: Rain stops play at Worcester - we do not lose any time or overs for 30 minutes
5:56pm - Jonny Bairstow is striding to the wicket at Headingley after Morkel claims his second victim, Adam Lyth. In between times, Dan Hodgson took 14 off Tim Groenewald's first over to keep the Vikings moving in the right direction.
After a brief delay to allow Moore to receive some treatment, Lancashire's innings has resumed.
5:48pm - After all that fanfare, both Wallace and Gale have been dismissed! Wicketkeeper-batsman Wallace follows up his six with a four off Jack Shantry before hitting another maximum! But two balls later, he's caught by Daryl Mitchell at short midwicket.

@LancsCCC on Twitter: Moore struck where you don't want to be. Everyone laughing but him. 14-0 in the third.
5:43pm - We have our first six of the evening! Mark Wallace starts in positive fashion for Glamorgan, striking three early fours, before putting the final delivery of Andre Russell's first over into the stands.

5:29pm - We're moments away from some live cricket! With eight games to come tonight, we're sure to have plenty of talking points before the end of the evening.
5:14pm - Derbyshire are the third team to choose to bowl first, at Headingley. So on a day which has seen a number of rain showers across the country, it looks like the captains are backing their bowlers to play an important role. We may have a few wickets to report early on!
5:09pm - Glamorgan will be aiming to set the home side a testing total at New Road after Worcestershire won the toss and elected to bowl.
Durham have also won the toss and elected to field first, meaning the Lightning openers Stephen Moore and Ashwell Prince will be thrust immediately into the action at the Emirates Durham ICG.
