However, almost immediately after the race got underway again, Fernando Alonso rolled to a stop at the side of the track on lap four after his car lost power. Jenson Button decided to pit at the start of the 10th lap for intermediate tyres, and the risk paid dividends as he moved up to third in the 14th lap.
Hamilton - who began the race behind Nico Rosberg - was determined the sneak past his Mercedes teammate to take the lead, but his race almost ended when he slid off the track in lap 27. However, the 29-year-old kept his composure and made a superb pass around the outside into turn one as he roared past Rosberg into first place just a lap later.
Button's race was turned upside down following a long pit stop which saw him emerge behind both Red Bulls, but after another pit stop saw him change to wet tyres he rejoined the race in fifth place.
The safety car was back on the track in the 45th lap as the rain began to fall yet again, and when the cars were pulled off the track shortly after, Hamilton was left celebrating his second successive victory.
