Play the 2012 U.S. Open at Louis Armstrong Stadium in Flushing, New York, has been suspended temporarily due to rain. The official delay was called 90 minutes into Monday's event, halting play during twelve round one matches in the men's and women's singles tournament, and judging by this photo from Reuters, the downpour was heavy.
Most of the major names in the tournament had yet to begin play when the delay was called at 12:30 p.m. ET, including Roger Federer, Kim Clijsters and Maria Sharapova. Defending women's champion Sam Stosur was able to complete her first round before the storm, with a 6-1 6-1 win over Petra Matric. Scattered showers are expected throughout the day on Monday in the greater New York City area.
