Apr.17 (GMM) As was predicted, heavy rain has disrupted the final session of the Barcelona test on Thursday.

Teams including Honda, Williams, Toyota, Renault, BMW, McLaren and Red Bull did venture onto the wet Circuit de Catalunya before lunch, but Ferrari - scheduled to run with Kimi Raikkonen today - did not.

Force India and Toro Rosso, meanwhile, have obviously heeded warnings that the rain could be set to continue into the afternoon, as they spent the morning session simply packing up.

The ambient temperature is a chilly 13 degrees.
