Lancashire's LV= County Championship Division One clash against Yorkshire has been abandoned, while there was no play on day three between Middlesex and Sussex.
No play was possible on day four at Headingley meaning the Roses clash was abandoned as a draw.
The visitors had been looking to build on their overnight 48-3, a lead of 130 despite Tim Bresnan's figures of 3-9, but miserable conditions in Leeds put paid to that and the game was abandoned less than 20 minutes after the scheduled start.
Lancashire's first-innings of 325 helped them to 11 points from the fixture, to Yorkshire's nine. For both teams, it was their third draw in six Division One games this season.
Durham and Nottinghamshire were also frustrated by the weather at Trent Bridge as their Division One match was drawn with no play possible on the final day.
A draw had always looked the likeliest outcome after only 83 overs were possible over days two and three but Gordon Muchall will have been disappointed to not have the chance to add to his unbeaten 158 as the champions ended on 335-4.
Batting at No 4, Newcastle-born Muchall stuck 22 fours and one six on his way to a 189-ball 158 but rain stopped him and Durham from eclipsing Nottinghamshire's first innings total of 377.
The home side finished the match with 10 points while the visitors head back north with 11.
Somerset maintained their unbeaten start to the LV=County Championship season but not in the manner in which they would have liked as the Division One clash against Warwickshire at Edgbaston ended in a rain-affected draw.
No play was possible on Wednesday in a match which had seen overs lost on all four days due to rain and Warwickshire never got the chance to add to their 294-5 in response to Somerset's first-innings 411.
James Hildreth (98) and Nick Compton (92) helped Somerset post a commanding total at Edgbaston, but Warwickshire's response was thwarted by the inclement weather.
Ian Westwood struck 99 and forged a 156-run stand with William Porterfield, who went on to score 118 before the rain came and prevented any further progress with both sides ending the match with nine points.
Elsewhere, rain meant that Middlesex's clash with Sussex was washed out for a third straight day.
Heavy rainfall in the capital meant that umpires Steve Garratt and David Millns called play off well ahead of the scheduled start time.
With just a day left and not a ball bowled in anger, a result looks virtually impossible at Merchant Taylors' School Ground in Northwood.
Middlesex have won four of their opening six games at the start of the season to top the Division One table, with Sussex fourth.
