Yorkshire and Nottinghamshire managed just 9.3 overs on day two of their LV= County Championship Division One match at Headingley.
The White Rose county were able to add 24 runs to their overnight total of 52-2 before the players were forced off the field due to bad light after less than an hour of action.
The rain then began to fall and although it seemed a resumption might be possible at one stage in the afternoon, umpires Martin Saggers and Alex Wharf called play off for the day due to a saturated outfield at 3.40pm.
Jack Leaning and home skipper Andrew Gale will resume on 35 and 23 not out respectively on day three; Yorkshire had already claimed maximum bowling points by dismissing Nottinghamshire for 205.
Ed Joyce completed his fourth century of the season and Steve Magoffin took 6-60 but Somerset still fought back to claim a first-innings lead in their clash against Sussex.
The 34-year-old Australian seamer Magoffin reduced Somerset, replying to 214, to 39-5 with an unplayable morning burst, but half-centuries from Craig Overton and Craig Kieswetter helped the home side to recover and take a 75-run first innings lead as they were all out for 289.
Magoffin, who has regularly terrorised Somerset since joining Sussex in 2012, added another wicket after lunch to take his overall haul against them to 36, but his efforts were not enough to stop the hosts from nudging in front.
Overton just missed out on his first ton, finishing on 86, but his impressive career-best knock, which included nine boundaries, was vital to Somerset's revival. Kieswetter posted a counter-attacking 65.
Sussex finished on 26 without loss in their second innings at stumps to trail by 49 runs going into the third day.
At Edgbaston, Warwickshire dismissed Lancashire for 286 on day two before digging in with the bat to reach stumps on 130-4.
A half-century from Tom Smith (50) helped the Red Rose county collect two batting points but Jeetan Patel (4-64) and Boyd Rankin (2-61) prevented the tail from wagging with significant effect.
The Bears lost Varun Chopra (9) and Ateeq Javid (7) early in their reply and when Laurie Evans edged Kyle Hogg to Paul Horton at first slip, the home side had crawled along to just 62-3 from 41 overs.
Will Porterfield eventually reached 50 off 177 balls and will resume alognside Tim Ambrose (12 not out) on day three, with Warwickshire trailing by 156.
