The teams had to dodge the rain at Jerez but the final four-day test before the first race of 2010 looks set to be dry.
The weather forecast for the Circuit de Catalunya is largely dry with temperatures in the mid-teens (C).
Some forecasts suggest a low chance of rain – 20-30% – on Friday and Saturday.
At least 11 teams will be at the home of the Spanish Grand Prix for the test but there’s still no sign of Campos Meta or US F1, or Stefan GP for that matter.
During the worst of the weather at Jerez Ferrari suggested the teams would be better off testing in drier (but more distant) venues. The teams have tested at Bahrain in recent years, though sand storms have caused problems at that circuit in past tests.
