Lewis Hamilton was able to go top of the time sheets in FP2 this afternoon in Monaco, just before rain hit the coastal city. Subsequent running was fairly limited due to the high risk of car damage when driving on the street circuit. Team mate Nico Rosberg was a lot closer to his Mercedes teammate this time around in FP2, going second fastest to Hamilton but still around seven tenths off of his team mates pace. 12 minutes into the session Manor's Roberto Merhi fell victim to the barriers of Monaco, colliding with them as he lost control while exiting the famous tunnel section. This meant the session was stopped for six minutes, and it was during the six minutes that the rain gradually started to introduce itself to the Monaco Grand Prix weekend. Once the session re-opened, all but one team opted to stay indoors and save risking cars and parts, the only team who ventured out was Lotus, sending Pastor Maldonado out equipped with a set of Supersoft tyres onto a circuit that was starting to become soaked in rain. Maldonado was immediately ordered to return to the pit lane due to the weather conditions. Drivers and teams remained quiet for nearly an hour as the rain began to fall, but with around half an hour remaining the sun broke through the clouds calling an end to the brief shower. It was only with 12 minutes remaining that drivers were sent out to try and get some running. This was possibly for the off chance that should there be any more rain throughout the weekend, the teams and drivers do have some data and experience to go off. The streets of Monaco are all the more challenging when wet, with painted road markings becoming more akin to ice than tarmac, transforming the racing line and subsequent braking areas around the circuit which is something the drivers benefit from in the case of rain come race day. Marcus Ericsson was the only driver who failed to set a time, due to an ERS problem with his Sauber.

There were no cars out on track or even an engine noise to be heard for over an hour today in Monaco due to the rain.
