Two days after the clash against Scarborough was ruined by rain, it was a similar story at the Kia Oval on Friday.
Only 5.3 overs were possible before the Group B match was abandoned due to regular bursts of heavy showers.
Morning rain meant play did not begin until 1.15pm, with the contest initially reduced to 34 overs per side, and Northants scored 31 for one wicket before more rain drove the players off at 1.40pm.
All that then followed for a sizeable crowd of more than 3,000 was a long afternoon of frustration as the Oval groundstaff worked hard between the showers to make conditions fit for a resumption.
A 4pm inspection did result in the umpires, Ian Blackwell and James Middlebrook, announcing that a 10-over game could begin at 5.20pm but – minutes later – more heavy rain swept in to confirm the no result, with both teams taking one point.
Steelbacks skipper Ricardo Vasconcelos who produced two sumptuous extra cover driven fours off Rikki Clarke and Matt Dunn, was the Northants wicket to fall – well-held above his head at third man by Dan Moriarty for 17 after the left-handed opener deliberately uppercut Conor McKerr’s fourth ball in the fifth over.
Emilio Gay remained eight not out, having been badly dropped at mid on by McKerr off Dunn from the final ball before the rain came again, and Ben Curran had faced just two balls.
Northants, still looking for their first group stage win after the two no results and one defeat from their first three fixtures, are next at home to Derbyshire on Sunday (start 11am).
Friday's other matches in Group B were also ruined by the weather, so the Steelbacks remain second bottom in the table.
With five matches to play, they are three points off the top three of Surrey, Glamorgan and Somerset who all have five points.
