We've seen in Melbourne that the Michelin runners struggle under wet and cold conditions. They have tested under wet conditions during the last 2 test sessions and it remains to be seen if they have made a step forward and closed the gap to Bridgestone in that area. Session starting in 2 minutes.

The weather forecast is for rain for the rest of today, light rain for tomorrow and showers for Race day. Session starting in 5 minutes.

Session starting at 11:00 AM local time. It is wet and raining at the moment with a temperature of only 8 degrees!
