3.27pm - The umpires call an early tea at the Essex County Ground, which has seen less than two overs since lunch.

Play resumes in the game between Surrey and Hampshire.

1.44pm - Steven Davies won't be going on to a big score, though. He's ousted first ball of the second session by Brad Taylor, leaving Surrey 180 for four.
Notts' Alex Hales completes a half-century, while the resumption at the Essex County Ground is delayed by rain.
1.40pm - Play resumes in the five games that took lunch at 1pm. There are a couple of batsmen who will be looking to go big this afternoon.
1.30pm - And that's lunch at Taunton, where Lancashire won the toss and made 47 for one in the first session against Somerset .
1.05pm - That's lunch everywhere but Taunton, where play did not start on time. It's been a good morning for the batsmen in Division One and the bowlers in the second tier.
Here's the current state of play:
Division One
Middlesex are 105 without loss having been put in to bat by Northamptonshire at Lord’s.
Nottinghamshire , having been inserted by Warwickshire , are 146 for two at Edgbaston.
Division Two
Surrey are 180 for three on day two of their meeting with Hampshire at the Kia Oval.
Essex put Gloucestershire in to bat and took six wickets for 56 runs, but the visitors to the Essex County Ground have recovered to 94 for six .
Worcestershire have been reduced to 56 for three against Glamorgan after winning the toss at New Road.
12.59pm - Jonathan Trott makes a telling contribution on his return to the first team at Warwickshire! Given three overs before lunch, the part-time bowler has Jaques caught behind for 77.
Lancashire lose a wicket, too, as Peter Trego removes Alex Davies for eight. The Red Rose are 30 for one.
12.55pm - Rogers drives James Middlebrook through cover for four to pass 50 - his 102nd first-class half-century. It's been a very good morning for the hosts, with bottom-club Northants being made to toil. Adam Rouse, fresh from his NatWest T20 Blast heroics , and Tom Smith have settled things down for Gloucestershire, with their seventh-wicket stand currently worth 35.
12.50pm - We are 10 minutes away from lunch and the batsmen are digging in. Chris Rogers will be looking to knock off the two runs needed to complete a fifty before the interval. His Middlesex side are 92 without loss at present.
12.25pm - And yet another wicket at the Essex County Ground! Topley removes Will Gidman for his third scalp, though - for a change - the edge was taken at second slip and not by the wicketkeeper. Gloucestershire are 56 for six!
Phil Jaques has a fifty for Notts, who are going along nicely on 93 for one.
12.06pm - Moeen Ali can't replicate his England heroics at New Road today as he skies Ruaidhri Smith to Chris Cooke, who ran back from short-leg to complete the catch. Two balls later Smith adds the scalp of Daryl Mitchell, leaving Worcestershire 39 for three. Play starts at Taunton.
12.01pm - If this was a game of Cricket Captain, I think Gloucestershire would 'accidently' be restarting their computer. They are now 37 for four after just 14 overs on day one. Ian Cockbain is the man out, with Masters taking a second wicket and Foster a third catch.
11.52am - Hampshire strike again at the Kia Oval and it's Solanki who perishes for 57, bowled by Briggs. Nottinghamshire's opening stand is ended on 55 as Rikki Clarke ousts Steven Mullaney for 21.
11.45am - There's good news from Taunton, where play will start in 20 minutes. Lancashire have won the toss and will bat. Surrey lose their first wicket of the morning and second of the innings, Rory Burns lbw to Danny Briggs for 36.
11.30am - Another one down for Gloucestershire! Topley has a second scalp as Hamish Marshall is pouched at point. And we have a first wicket of the day away from the Essex County Ground, with in-form Michael Hogan accounting for championship debutant Richard Oliver at New Road.
11.20am - It looks a very important toss to have won for Essex. They have Gloucestershire two down in the opening four overs. Chris Dent falls victim to Reece Topley, with Foster taking a superb catch behind for his second dismissal.
11.05am - Not exactly the start Gloucestershire had in mind. David Masters strikes with the third ball of the contest, finding Will Tavare's edge and James Foster does the rest.
Vikram Solanki started the day unbeaten on 44. Two fours from the first three deliveries he faces this morning sees him raise a fifty.
11am - We're still awaiting an update from Taunton, but the other games are getting underway.
10.35am - We have news from the middle! Warwickshire, who include Jonathan Trott, elect to field against Nottinghamshire, while Northamptonshire and Essex do likewise at Lord's and the Essex County Ground respectively. Going against the grain, Worcestershire will bat first at New Road.
10.25am - Some sad news from Worcestershire, who have announced the passing of academy director and former batsman Damian D'Oliveira at the age of 53 following a two-and-a-half-year battle with cancer .
10.10am - While we wait for the tosses to take place, read our previews for the games in Division One and Division Two .
