|County Championship Division One, Cricket Field Road|
|Close, day two: Surrey 124, Sussex 90-6|
|Sussex 3pts, Surrey 2pts|
Surrey's Stuart Meaker claimed three Sussex wickets as only six overs could be bowled on the second day at Horsham.
The hosts resumed on 81-2 and they could only add a further nine runs as Meaker claimed the wickets of Michael Yardy, Joe Gatting and Ben Brown.
Murali Kartik also had Luke Wright caught behind by Steven Davies as Sussex have fallen from 80-1 to 90-6.
However, a sustained period of rain saw umpires Peter Willey and Neil Hartley call off play in the early afternoon.
With two days remaining, Sussex trail by 34 runs with four first-innings wickets remaining after Surrey posted a total of 124 all out on Thursday.
Meaker, who is hoping to add to his two England one-day international appearances in the series against Australia later this month, has now claimed 30 wickets from six Championship matches this season.
He had Yardy caught by Mark Ramprakash at gully, ripped out Gatting's off stump and trapped Brown lbw.
Sussex's Luke Wells will resume on Friday on 38 not out, while Naved Arif has faced seven balls but is yet to score.
VIEWS FROM THE COMMENTARY BOX
BBC London 94.9 commentator Mark Church:
"In the six overs possible Surrey forced their way back into the game.
"Stuart Meaker did the damage getting rid of Michael Yardy, Joe Gatting and Ben Brown in quick succession.
"Murali Kartik had Luke Wright caught behind by the returning Steven Davies (who had done a round trip to Edgbaston) and Sussex had lost four wickets for the addition of just nine runs.
"Luke Wells remains unbeaten on 38 and with a weather forecast that seems to be improving a very interesting couple of days lie in wait at Horsham."
BBC Sussex's Adrian Harms:
"Rarely can so much action have been packed into a days play where just six overs were possible.
"Sussex lost four wickets for nine runs to completely change the balance of the match, bearing in mind they had been 80-1 just before the close yesterday [Wednesday].
"The heavy rain in Horsham has left puddles on the outfield and the ground staff will be working overtime if there is to be any chance of a prompt start in the morning."
