Rain a real possibility for raceday in Kuala Lumpur
Welcome to the first day of the Malaysian Grand Prix, where the teams will be keeping a closer than usual eye on the weather.
The general forecast all through the race weekend is for cloudy skies but high temperatures and high humidity. Scattered showers are likely to be a feature too.
Today it will reach 32 degrees Celsius, with a 60 percent chance of rain. On Friday and Saturday the temperature should hit 33, again with scattered thunderstorms, and there is a 50 percent chance of rain at this stage on raceday, when the temperature is expected to reach 32.
The Sepang Circuit remains unchanged from Hermann Tilke's original and highly successful and distinctive design, and is situated close to the Kuala Lumpur International Airport and a half hour drive from Kuala Lumpur itself.
Despite the clouds and the threat of periodic thunderstorms, the event is expected to be one of the hottest of the season.
