1) Storm a comin': The forecast for Saturday and Sunday at Singapore is for rain and stormy weather. With temperatures at night expected to be in the mid 20s expect a lot of mayhem in qualifying and the race.
2) Playing it cool: With conditions expected to be wet and cool, expect the more aggressive drivers to shine as their driving style will probably make it easier to generate heat into the tyres.
3) It's up to Seb: Sebastian Vettel can wrap up the title with a third place finish so depending on whether he plays it safe or tries to wrap up the title with a flourish could determine how the rest of the front runners fare.
4) Night lights: Despite the impressive lighting at the Singapore track it is no mean feat to drive an F1 car at full speed with the aid of floodlights without any lights on the car. One driver or another will always be caught out by the experience.
