The matches at AFC Fylde and Southport both had to be halted after heavy rain caused their pitches to be waterlogged.
Fylde were 4-0 up against Leamington when a heavy downpour caused the match to be stopped in the 60th minute. The referee soon deemed that it could not continue.
Meanwhile at Southport, the Sandgrounders' game against Peterborough Sports was halted shortly afterwards. The players left the pitch, with the referee confirming the game had been abandoned just after 5pm.
Both matches will have to be replayed at a later date.
