With more snow in Manhattan than on some of the mountains around Vancouver, weather continues to be a worry as the Winter Olympics open tonight.

First came fears of not enough snow at Cypress Mountain, the freestyle and snowboarding venue. That area got 4 inches of snow Wednesday, on top of earlier emergency air-and-truck transfers of powder — but rain and fog yesterday hampered moguls training.

The fog and rain on the downhill course in Whistler yesterday also forced a halt to the women’s training session after American Stacey Cook slammed into the safety netting.

Temperatures there hovered above freezing — making the course soft.

Tonight’s opening ceremonies will be held indoors, in the 55,000-seat BC Place Stadium — and that may be a blessing, as the forecast predicts showers through the weekend.

Organizers and competitors are keeping their fingers crossed that what snow there is will survive the recent record-breaking warm, wet weather.

{CLUB}A female Russian hockey player has been reprimanded for the first doping violation of the Olympics.

The IOC yesterday said Svetlana Terenteva tested positive for a stimulant prohibited in competition but not out of competition. The substance is called tuaminoheptane.

The IOC says Terenteva admitted using a prescription drug for a cold last month but stopped using it Feb. 3, a day before the Olympic drug-testing program began.

She was reprimanded but not disqualified.

{CLUB} Meanwhile, with more than 30 athletes already prevented from competing in Vancouver, World Anti-Doping Agency chief John Fahey predicts cheats are more likely than ever to be caught at these Olympics.

Fahey confirmed yesterday that more than 30 athletes had been excluded for breaking anti-doping rules over recent months, and that the cases include a mixture of positive samples and failure to comply with testing protocols.

He refused to give details of the athletes, sports or nationalities.

“The one thing I will declare: Athletes who seek to cheat at these games, it’s more likely they’ll be caught than in any other games in our history,” Fahey said.

About 2,000 drug tests are being carried out during the games, including surprise, out-of-competition checks at training sites and other locations outside the venues.
