Today's race meeting at Fakenham was finally claimed by frost following a second inspection.
Officials at the track called off the fixture shortly after 10 a.m.
Clerk of the course David Hunter was "fairly confident" the card could be run after an initial 8 p.m. inspection but temperatures failed to rise sufficiently in the ensuing hours.
There is now no jump racing in Britain today leaving two Flat fixtures on the all-weather at Lingfield and Wolverhampton.
