Leicestershire were bailed out by the rain in Cardiff as Glamorgan's victory charge was aborted, needing just two wickets on the final day of their LV= County Championship Division Two clash.
After resuming on 168-3 the Foxes were stripped back to 204-8 courtesy of three wickets from seamer Michael Hogan before the weather took hold once more.
With play starting just before 2pm, West Indies international Ramnaresh Sarwan failed to add to his overnight total of seven before being caught behind off the bowling of Hogan, who revelled in the overcast conditions.
Mark Wallace then caught Angus Robson for 81 off the bowling of Jim Allenby, while Hogan had Rob Taylor taken behind for a duck and when Allenby switched ends to clean up Anthony Ireland for a duck the end was nigh with Leicestershire 182-8.
Niall O'Brien and Nathan Buck dropped the anchor of resistance, though, and kept themselves afloat despite light and rain causing the players to go off, on, off, on and back off again before the draw was called with Glamorgan taking 12 points and Leicestershire seven.
The Division Two match between Essex and Surrey also ended in a draw after rain washed out the final day of play in Chelmsford before a ball could be bowled.
Only 16 overs of play were possible on day three of the weather-affected contest, with the visitors reaching 261-7 as they passed Essex's first-innings total of 228.
However, further heavy downpour left the pitch unplayable on Thursday morning, with captains James Foster and Gary Wilson shaking on a draw before play could get under way.
Essex have now drawn four of their opening six matches of the season, leaving them fourth in the Division Two standings.
Derbyshire's search for a first win of the County Championship campaign goes on after their Division Two clash with Gloucestershire ended in a draw with play abandoned before it began on day four.
Bad weather had affected the match from the start, and with wet conditions at the County Ground there was little prospect of a result with the visitors still in their first innings.
Gloucestershire struggled to 66-4 on Tuesday, replying to Derbyshire's 278, but were comfortable in the knowledge that a draw had long been on the cards.
Both sides take eight points each but that was not enough to prevent Derbyshire from slipping to the foot of the table, while Gloucestershire are only two places higher in seventh after three draws and two defeats in their opening six matches.
At Tunbridge Wells, Kent's Division Two meeting with Worcestershire was abandoned as a draw after inclement weather on the final day.
No play proved possible on Wednesday and a decision was taken to call off the game after a pitch inspection at 3pm.
A result had seemed unlikely anyway with the match having advanced little on day three. Worcestershire were 67 without loss in their first innings, replying to Kent's 258.
However, eight points are enough to see Worcestershire maintain second place, just four adrift of Hampshire, and seven points for the hosts has elevated them to fifth.
