US Open golf officials have made contingency plans because of a bleak weather forecast on the eve of the championship at Bethpage State Park in New York.
Extensive rain over the last six weeks has saturated Bethpage's fearsome Black Course and further showers are expected on Long Island for the next four days with thunderstorms forecast for the final round.
Meanwhile Tiger Woods is expecting a boisterous atmosphere for the championship in New York, but says it won't compare with the last US Open at Bathpage seven years ago when the city was still recoiling from 9/11.
Woods believes New Yorkers used big sporting events to help them get over the tragedy.
Tiger Woods is bidding for his fourth US Open title and 15th career major.
