South Africa were permitted just 90 minutes of batting before rain washed out the remainder of the middle day of their final warm-up match before the first Investec Test.
The tourists moved from 31 for one to 108 for two against Kent, in 22 overs following a delayed start because of overnight rain and before a lunchtime storm broke over Canterbury.
Hashim Amla and Jacques Kallis were unbeaten against a home pace attack comprising seasoned pair Charlie Shreck and Simon Cook as well as England Lions' Matt Coles and 20-year-old Ivan Thomas.
A slow pitch, which meant some hard work for Dale Steyn and Co on day one, gave South Africa's batsmen the opportunity to fine-tune their preparation for the first Test of three against England - which will start at The Oval on Thursday.
All four of the top order who have tried here - captain Graeme Smith was the only man out last night - have made it into the 20s.
Smith's fellow opener Alviro Petersen was the batsman to go in the play possible this morning, lbw pushing forward when Cook got one to hold its line up the slope.
Amla and a fluent Kallis were then untroubled to add an unbroken 34, until the forecast rain arrived with a vengeance.
On leaving the field, South Africa discovered the latest International Cricket Council rankings update has demoted them from second to third behind England - fresh motivation perhaps to try to usurp their hosts at the top of the table once the rain relents this summer.
They can expect to be back on the pitch early tomorrow, if the weather allows.
When play was called off shortly after lunch, it was also announced that a 1030am start is planned on a final day which will contain 98 overs.
Assistant coach Russell Domingo is unperturbed by either South Africa's relatively short preparation time before the first Test, or their minor slide in the ICC rankings.
"I reckon if we were here for a month we'd still struggle to get in a lot of preparation," he said, as he surveyed a waterlogged outfield.
"We knew this was going to happen, so there's nothing we can do about it.
"I'm not worried. We had such a good week of preparation in Switzerland - the guys were almost saying 'we're mentally ready to play already'.
"Whether we practised with 10 games, or three games or two games, I don't think it would make too much difference - because the guys are mentally ready. They're fired up to go and do this."
