Racing at Saturday's Ulster Grand Prix was curtailed just after 5pm after poor weather conditions gave organisers little option other than to abandon the remaining three races.

Both the opening Superbike and Lightweight/Ultra-Lightweight races were stopped early due to rain falling and conditions worsened over the next hour with visibility at the top part of the circuit becoming more and more reduced.

In a day which started in bright sunshine, accidents in the Superstock and Superbike races resulted in lengthy delays, putting pressure on the organisers and race schedule with rain predicted to be falling around 4pm. Sure enough, as the day wore on the clouds darkened and almost on the dot of 4pm, the rain began to fall, initially as a few spots but gradually getting heavier.

After the Lightweight/Ultra-Lightweight race had been stopped, organisers waited 30 minutes to see if the weather would clear but the opposite occurred with the rain getting heavier and the mist getting thicker.

Racing was eventually called off with the second Supersport and Superbike races and Supertwins race falling victim to the weather.
