Fernando Alonso doesn't look to be heading out any time soon. He's not in his McLaren and is instead sat at a table watching the action.
Lewis Hamilton can't beat his team-mate into P1 as he clocks a 1:48.853, half a second off Nico Rosberg's time.
Meanwhile replays just catch Pastor Maldonado, who currently has the sixth fastest time, off the circuit and on the artificial grass at Turn 2, having run well wide. Sebastian Vettel also has a brief excursion off the circuit. Still wet out there.
A few drivers struggled to keep the car on the circuit in first practice because of the wet surface and Kimi Raikkonen is the first to go off in FP2, running onto the artificial grass at the final chicane.
The clouds are starting to lift and the spray kicking up from the back of the cars is getting a little smaller as conditions continue to improve.
Nico Rosberg gets up and running in FP2 with a 1:48.300 that takes him straight to the top of the leaderboard.
Kimi Raikkonen goes second fastest with his first effort of the day, just under a second slower than Daniil Kvyat's early pacesetter.
No rain falling at the moment but still plenty of standing water on the track. "Look out for the rivers," Nico Rosberg is warned on team radio.
Meanwhile, no hanging around for our fist timed lap in FP2 as Daniil Kvyat is round in 1:49.374.
Max Verstappen is not going anywhere soon, there is a screw loose in his Toro Rosso...
"When they were tightening up the bodywork one loose screw fell in and they had to take off the bodywork to find it,"Verstappen tells BBC Sport's Jennie Gow. "Hopefully it won't be too long before I'm out."
Daniil Kvyat, on the intermediate tyre, does a practice start before blasting out onto the circuit.

The green light is on and the circuit is open. Who will be the first to pop their head out for a look?

Quote Message"It is still a wet condition but it has dried up a little bit. I think we will see a bit more running than we did in the first practice."
It may have been an uneventful first practice session, and one that was perhaps not conducive with trying to stay awake in the early hours of the morning, but it is nevertheless still a challenge for drivers, as Lewis Hamilton explains in his latest column:
"When you're driving, you are normally looking really far ahead. But in the wet, you can't see a lot at the best of times and if you are behind a car, it is like you are driving through thick fog.
"It is a bit like driving on ice - the acceleration and braking have to be more progressive and the car is more unpredictable."

No asphalt rusk for Nika Lauda and Toto Wolff, however. All about the Wiener Schnitzel.
