Kent v Gloucestershire
It's cold and gloomy here, but the players are eager to get started.
Daniel Bell-Drummond will face the first ball from Matt Taylor, who is bowling his first ball in senior cricket for Gloucestershire this season...
Somerset v Essex (17:30 BST)
Spare a thought for the Essex press officers who look like they've endured a bit of a journey to forget from Chelmsford to the West Country this evening.
Well, let's hope they arrive soon - the players are on their way out at Taunton.
Lancashire v Yorkshire (18:30 BST)
It's so rare to see Joe Root in a Yorkshire shirt these days, I had to dig out a picture of him in one-day colours from about five years ago!
However, this evening the England star is back in the White Rose squad, along with England teammate Jonny Bairstow, to face their biggest rivals.
Lancashire have one or two superstars themselves - none bigger than Jos Buttler.
We'll have team and toss news from Old Trafford at about 18:00 BST.

The T20 Blast is only a couple of weeks in, but we've already seen blistering centuries, five-wicket hauls and record-breaking team totals.
Worcestershire are sitting pretty at the top of the North Group with three wins out of three - but are one of only two teams never to have been to Finals Day.
So that brings me onto today's Get Involved question - which four teams do you think will make Finals Day?

Jim Allenby has won the toss for the home side, but the Taunton crowd will have to wait for the World Boss to stride to the middle as he's invited Essex to bat first.

The Spitfires, who also played less than 24 hours ago when they lost to Hampshire, are unchanged.

Somerset v Essex (17:30 BST)
Hopefully the weather at Taunton this evening will be a bit more to Chris Gayle's liking!
After spending two months in red hot conditions at the IPL, Gayle had a bit of a shock at Hove on Wednesday when he stepped into 10 degrees and an ice cold wind.
The 'World Boss' said he needed time to acclimatise after he was bowled for just five on his Somerset return.
Well, the weather is set fair in the west so we could well be in for some Gayle fireworks.
