Northamptonshire were denied their first win in this season's Clydesdale Bank 40 by the rain, after captain Alex Wakely and veteran David Sales made half-cenuries against Derbyshire.
The Steelbacks posted 220-8 from their 40 overs as Wakely made 85 off 100 balls and Sales blasted 74 from 80 deliveries, with Mark Turner taking 4-38.
David Willey and Oliver Stone then took early wickets to reduce the Falcons to 19-2 before the heavens opened three overs before a result was possible.
Sales and Wakely came together in the eighth over after pace bowler Turner had removed Kyle Coetzer (9) and David Willey (21) in quick succession.
The pair led an inspired fightback for the hosts, adding 162 for the third wicket as Derbyshire's attack struggled to stem the flow of runs.
The partnership was finally broken when Sales, making his return from injury, was bowled by Turner and three balls later, Rob Newton chopped the same bowler onto his stumps after making a single.
Steelbacks wicketkeeper David Murphy (12) launched Tim Groenewald to Derbyshire captain Wayne Madsen at mid-off before Wakely walked when he was caught and bowled by Groenewald three balls later.
Chasing 221, Derbyshire should have lost Australian Usman Khawaja in the first over but he was dropped by Sales at second slip when he had yet to score.
But Chesney Hughes was to depart for 16 when he smashed Willey straight to Burton, who was standing at deep square leg before Durston was trapped lbw by Stone for a two-ball duck.
With the Falcons on 19 for two, heavy rain stopped play at the start of the seventh over and it only increased in intensity, making any further play impossible.
Both teams therefore earned a point from the match, although Northamptonshire will be left frustrated after putting themselves in a winning position.
