The first innings has been declared over. Play has to resume by 21:57 to fit a five-over chase in.
The rain has taken a turn for the worse and the players have had to go off.
Chris Cook caught by Max Waller. Tim Groenewald with the wicket.
An incredible reverse sweep over point for a maximum. What a shot.
Andrew Salter caught and bowled by Max Waller. Talk about instincts.
A fan in the crowd catches Ingram's six (just before his wicket fell) and doesn't spill a drop of his pint. He looks very pleased with himself. And so he should.
Lewis Gregory has another wicket. Aneurin Donald shanks one high and is caught at midwicket.
Aneurin Donald takes on the new ball in style, scooping for a cheeky maximum.
David Lloyd caught behind for one run off the bowling of Lewis Gregory.
David Lloyd and Aneurin Donald open the batting for Glamorgan. We'll bring you updates with clips from this point forwards.
Somerset skipper Jim Allenby: "We’re not worried [about the start we’ve had] but a bit disappointed. We haven’t started well with the bat. We need to start upping our game and tonight we should be able to do that."
Glamorgan captain Jacques Rudolph: "Batting first gives us a decent opportunity to put some runs on the board. We’ve got quite a few X-factor bowlers so that does allow us to go big up front."

Somerset won the toss and they opt to bowl first.
Play is set to start at 19:35. The toss is imminent.
The umpires have come out without umbrellas, which is a positive sign apparently. Conditions do seem to be improving slightly.
Glamorgan have won one and lost one so far, losing their opener to Hampshire and then winning against Sussex.
Somerset, however, have lost both their opening Blast matches to Surrey and Essex.
No sign of the drizzle clearing yet but we don’t start losing overs until 19.35 so there's still hope.
Hello and welcome to our live coverage of tonight's T20 Blast fixture as Glamorgan host Somerset. Unfortunately the toss has been delayed due to rain.
