The Honda Grand Prix of St Petersburg will run today (Monday) after heaving thunderstorms forced IndyCar officials to postpone Sunday's race.

The event becomes the first to be postponed by the weather since the Indy Japan 300 in 2008, which was eventually won by Danica Patrick.

Points leader Will Power will start the race from pole position having led the way through qualifying on Saturday.

"I think it was a good decision to postpone the race for the safety of the fans and the teams," Newman Haas Lanigan driver Hideki Mutoh said. "If we were to go out and try to race maybe there would only be one car that would finish.

"The fans deserve to see a good race so I hope the ones that were here are able to come back."
