Lancashire v Kent - start delayed by rain
The umpires have inspected the pitch at Stanley Park in Blackpool and it's not great news yet unfortunately.
An early lunch will be taken at 12:30 BST.
We will keep you updated with any further news of a start time if and when we get it.
Nottinghamshire v Somerset 8-1
Lewis Goldsworthy hammers one through cover from Brett Hutton but Notts skipper Haseeb Hameed does very well indeed to get down and prevent a certain boundary.
It's nipping about out there but Goldsworthy is still trying to go on the attack as he tries to drive but inside edges and almost drags on.
Just the one from the over for Jordan Hermann in the end.
Procter c Bracey b Clarke 6 (Northants 25-2 v Glos)
This is turning into a very decent county debut for Kristian Clarke, who has now removed both Northamptonshire openers!
Luke Procter was trying to pull his bat out of the way as the ball nipped back outside off stump - but he wasn't quick enough and there's a faint edge through into the wicketkeeper's gloves.
Bit of rebuilding for the home side to do as Clarke's first ball fizzes just past the outside edge of new batter Nathan McSweeney.
Durham 13-0 v Derbys
Four slips in place for Mo Abbas, but Ben McKinney collects the first boundary of the game at the Riverside as he steers the Pakistan seamer through the covers. Just a tad overpitched and that was very well timed.
Yorkshire 22-0 v Warwickshire
It's an over of extras from Keith Barker as he bowls three no-balls in a row.
Four leg byes are also added to the Yorkshire total.
Nottinghamshire v Somerset 7-1
Lewis Goldsworthy comes to the crease and he now faces the challenge of Fergus O'Neill, who is looking dangerous here.
Goldsworthy survives the rest of the over after Josh Thomas was caught in the slips but not without O'Neill beating the outside edge from the final delivery.
Sussex v Glamorgan 12-2
Anyone who has seen Kiran Carlson giving the ball some hammer in the T20 Blast might be surprised that his first 13 faced at Hove have been scoreless. He is finally off the mark with a single as he drives Sean Hunt into the covers.
Thomas c Haynes b O'Neill 0 (Nottinghamshire v Somerset 7-1)
Josh Thomas has been tied in knots early doors by Fergus O'Neill and now he's gone for a duck!
Fergus O'Neill's line just drifts slightly down the legside from the first ball of the over and it flicks Thomas' thigh pad on the way through and runs all the way for four leg-byes down to fine leg.
But the very next ball, O'Neill is back on a teasing length outside off and Thomas plays slightly across the line and can only edge straight to Jack Haynes at third slip, who takes a decent catch.
Tough start for Somerset. Great start for Notts.
Tribe c Simpson b Unadkat 6 (Sussex v Glamorgan 11-2)
Not the greatest of shots by Asa Tribe who flashes at one outside off stump from Jaydev Unadkat and is caught behind by John Simpson.
"He didn't need to play at that," is the shared opinion of BBC radio commentators Adrian Harms and Nick Webb.
Yorkshire 12-0 v Warwickshire
Yorkshire managed just six runs in the first five overs after being put into bat at Scarborough.
Will Luxton does get things going a bit in the sixth over with a two and a four off successive balls from Ethan Bamber.
Nottinghamshire v Somerset 2-0
Brett Hutton opens from the other end for Notts, so we will have to wait a little longer to see Pakistan international Mohammad Ali bowl on his County Championship debut for the defending champions.
A tidy over from Hutton and just a couple off it for Jordan Hermann, tickling the final ball down to fine leg for two.
Northants 19-1 v Glos
It's an all-Kiwi attack for Gloucestershire at the start of this game, with Will Williams and Kristian Clarke both getting the ball to move around in helpful overhead conditions.
Williams has been tidy so far, sending down 11 dot balls - the exception being thumped over extra cover for four by Calvin Harrison.
Harrison has nine to his name, with home captain Luke Procter yet to get off the mark.
Nottinghamshire v Somerset 1-0
Fergus O'Neill ends the first over with a length delivery outside off and Josh Thomas tucks his bat in to let it pass through to Joe Clarke behind the stumps for Notts.
Somerset survive the first six balls at a very gloomy Trent Bridge.
Geddes c Libby b Taylor 5 (Middlesex 13-1 v Worcestershire)
Jake Libby takes an excellent low catch at third slip and Ben Geddes is gone for 5 with Tom Taylor taking the wicket.
Worcestershire will be relieved as some wayward bowling had seen them concede early boundaries.
Durham 6-0 v Derbys
As you might expect, there aren't many freebies being handed out at the Riverside.
In-form Ben Aitchison's first couple of overs with the new ball have yielded just three runs and Mo Abbas is typically right on the money at the other end.
Nottinghamshire v Somerset 1-0
Slightly delayed start, on, off and now back on again at Trent Bridge.
The players are coming back out after a brief rain shower halted proceedings.
Fergus O'Neill has one ball remaining in the opening over and it's Josh Thomas who will face it.
Leics v Essex (start delayed)
There's been some mopping up going on at Grace Road after overnight rain and showers this morning and the umpires have had a look at the pitch, but decided it's not yet playable.
They'll return for a second inspection at 11:30 BST - so let's hope they'll be in a position to give the green light then.

Wow, the picture at 11.05... are you sure that's not the Grace Road outfield? Even my military medium would stand a chance on that... if I could pitch it!
Mark, Herne Bay
That photo of the pitch at Grace Road is hilarious. I was planning to go and watch tomorrow but fear all 40 wickets might fall today!
Tad, Leicester
Just to remind you what Mark and Tad are referring to, this is the track at Grace Road for Leicestershire's match with Essex, where the start has been delayed because of adverse weather conditions...

Nottinghamshire v Somerset 1-0
Well, that was short-lived. The umpires are taking the players off after just five balls from Fergus O'Neill.
