Wednesday's meeting at Exeter has been abandoned following a second inspection at lunchtime.
Clerk of the course Barry Johnson took an initial look at 8am and was hopeful of conditions improving after seeing some of the snow on the track melt overnight.
However, the weather has turned colder once again in the south-west and Johnson reports the track to still be unraceable following another check shortly before 1pm.
Thursday's meeting at Fakenham has been abandoned due to snow.
Clerk of the course David Hunter inspected the track at noon on Tuesday but was forced to admit defeat.
