Today's meeting at Kempton has been abandoned due to snow, meaning there is no racing in Britain and Ireland today.
Kempton officials initially gave the fixture the go-ahead early on Sunday morning but the situation quickly deteriorated.
Acting clerk of the course Sarah Dunster said: "The temperatures have dropped quite a bit in half an hour.
"There is now freezing ice crystals in the track, so we've made an early call to abandon."
Monday's afternoon meeting at Kempton will be subject to an inspection at 9am.
