Division One leaders Surrey at home to Essex
Second-placed Hampshire play Gloucestershire at Cheltenham
Notts, leaders of Div Two, away to Derbyshire in East Midlands derby
Somerset 116-2 v Yorkshire
Runs have been flowing since the resumption in Taunton.
George Bartlett hit Matthew Waite for back-to-back fours at the end of the 31st over, and Tom Abell has just edged the lively Shannon Gabriel past gully for another boundary.
Gloucestershire v Hampshire 170-1
Nick Gubbins and Felix Organ have brought up the 50 partnership for the second wicket for Hampshire. Organ is now on 73.
They seem determined to lay the platform for a very big first innings total.
Northants 151-5 v Lancashire
Rob Keogh has moved to 34 with five boundaries, as he tries to play the lead role for Northants.
Less than 20 overs left today.
Somerset 99-2 v Yorkshire
After a delay of almost two hours, play is back under way at Somerset.
Tom Abell and George Bartlett resume batting for the hosts, Matthew Waite has the ball in hand for Yorkshire.
Northants 134-5 v Lancashire

There has been a strong breeze blowing down the ground from the Pavilion end of the ground all day, but it’s not really bringing much relief. It’s like standing in front of a giant hairdryer.
Dane Vilas has only won one toss all season in the Championship and I’m sure his players were giving him a pep talk beforehand saying ‘this is the day, skip.’
Sadly for Lancashire, his poor tossing record continues and under the circumstances they’ve bowled well. They have stuck at it, on an uncomfortable afternoon.
Warwickshire 12-2 v Kent 165
Matt Henry may have fancied this after watching Ollie Hannon-Dalby's efforts this morning and he shows why.
A crackerjack of a delivery, he squares up Alex Davies and with a hint of movement, the edge flies into Zak Crawley's hands low down at second slip.
A terrific riposte from Kent.
Derbyshire v Notts 233-1
Image source, Getty ImagesJust moments after Ben Duckett reached three figures, Haseeb Hameed tucks George Scrimshaw away for a single and brings up his own hundred off 153 balls.
Like his partner, it's his third of the season and Hameed has also passed 700 Championship runs for the season in this innings.
Derbyshire v Notts 224-1
Ben Duckett comes down the track and flicks a Mattie McKiernan full toss away for four to reach a 118-ball century. It's the left-hander's third Championship hundred of the season and 22nd of his career.
Over to you, Haseeb Hameed.

Matt Milnes has the first one for Kent.
He produces a beauty to get the edge of Dominic Sibley's bat and Sam Billings does the rest.
Essential for Kent and they need a few more wickets with the new ball.
Surrey v Essex 153-6
Essex pass 150 as Adam Rossington jams the bat down on an inswinging Kemar Roach yorker and the ball runs away past gully's left hand for four runs.
Gloucestershire v Hampshire 138-1
Two fine strokes from Nick Gubbins off Zahar Gofar as Hampshire try to show more intent after tea.
The 90 minutes after lunch would have been ideal for a siesta!
Derbyshire v Notts 215-1
They are on a drinks break in Derby. Haseeb Hameed is 95 not out, Ben Duckett has 96 - both just one blow away from a century.
Gloucestershire v Hampshire 130-1
A lovely stroke from Felix Organ takes him into the sixties. He's now 61 not out.
The Hampshire opener has 23 overs left today to try to get to three figures.
Surrey v Essex 147-6
Another over ticks by at The Oval and it's a maiden from Kemar Roach to Simon Harmer. Just three runs from the last three.
Northants 134-5 v Lancashire
Three wickets in the session for Lancashire, who will be well pleased after Northants opted to bat this morning.
The home side have had players get in and get out and they could do with a big contribution from someone on what looks a good pitch.
Northants 124-5 v Lancashire
A second wicket for Washington Sundar as he traps Ryan Rickelton in front.
The ball might have been going down as Rickelton tried to work it to leg, but the decision is final.
Another useful wicket for Lancashire.
Warwickshire v Kent 165 all out
Last man Matt Quinn does not hang around. He tries to hit the left-arm spin of Danny Briggs over the top but does not clear Craig Miles at mid-off.
The end of a very poor batting display. Put in on a pitch with a green twinge, to only last 40 overs is not much to write home about.
Ollie Hannon-Dalby's 6-40 was the standout.
And my sincere apologies to Warwickshire captain Will Rhodes. You were right to bowl first. I was wrong.
Somerset 99-2 v Yorkshire
Good news, they'll restart in about 40 minutes at Somerset.

Gloucestershire v Hampshire 123-1
While those Kent wickets were falling, tea has been called at Cheltenham.
A shortened session of 24 overs for 44 runs for the loss of Ian Holland. Quiet cricket.
Warwickshire v Kent 164-9
Navdeep Saini lasts three balls and it's a second wicket in the over for Henry Brookes.
Saini goes to leave it but forgets to move the bat and it is guided into the hands of Sam Hain at second slip. Catching practise.
Warwickshire will be batting soon enough.
