The Singapore Grand Prix this weekend could play a deciding role in the race for the 2010 F1 title with forecasts suggesting that the race weekend is set to be hit by wet weather conditions.
While rain makes events far from easy for drivers on a traditional circuit, the added element of racing on streets and of competing under lights could ensure that Singapore proves to be something of a lottery.
Rain has been falling during Thursday on the Singapore streets and is expected to return for both Friday practice and qualifying on Saturday – the latter starting under darkness at 10pm.
Further rain is also due on Sunday, albeit before the race itself gets underway, which means that the circuit may have dried out before the F1 cars take to the track with both Formula BMW Pacific and Porsche Carrera Cup Asia races due to take place before the main event.
However, the prospect of rain affecting the Singapore weekend for the first time raises interesting questions over the impact the race will have on the five-way fight that has developed for the championship crown.
One man who no doubt won't like the idea of a wet race is Mark Webber, given that the championship leader has yet to even finish the Singapore race. Back in 2008, he suffered transmission issues that left him to park up while last year's event saw him crash out after encountering brake problems.
Rain therefore could play to the strengths of defending race winner Lewis Hamilton, reigning champion Jenson Button or Fernando Alonso – all of whom have shown what they can do when conditions aren't at their best.
Button has already won in the wet this season and his smooth driving style could be well suited to tricky circuit conditions, while Hamilton also won in the rain at Spa. Alonso meanwhile has yet to finish off the podium in Singapore and won't plan on doing so this time around.
That leaves Sebastian Vettel as the fifth driver in the mix and rain is unlikely to be welcomed by the German, who failed to impress when it rained at Spa and has been known to be somewhat erratic when under pressure. Rain would only increase the chances of something going amiss for the German.
But why would rain be such an issue in Singapore compared to anywhere else?
