Monsoon-like conditions, accompanied by swirling winds, arrived just moments before Australia's Casey Stoner, on pole position, was due to lead defending world champion Valentino Rossi and the other riders away on the warm-up lap. "It's just unlucky with the weather," said Australian Ducati rider Stoner, the 2007 world champion, who was bidding for a third successive win here.
