The number of athletes has risen with the temperature.

Registration for the Empire State Winter Games is up to 1,571 “and counting,” spokesman Sandy Caligiore said Monday afternoon. It was around 1,300 last week, he said. Last year’s games had more than 1,600 participants, a record. There were fewer than 900 five years ago, the first year local agencies and municipalities took over the event after the state dropped it in 2010. These are the 36th annual Empire State Winter Games, with competitors ranging in age from children to senior citizens.

These games have a major economic impact. ESWG organizers estimate an average of two family members or friends will accompany each athlete. At the present registration, that would mean an influx of about 4,800 people for the events Thursday through Sunday, spread out through Lake Placid, Saranac Lake, Tupper Lake, Paul Smiths and Malone.

Meanwhile, snow is quickly disappearing with temperatures in the high 40s Sunday and Monday. It looked like mud season outside Monday, and another 40-plus-degree day is forecast for Wednesday, with a 100-percent chance of rain to boot. Nordic skiing events are considered the most vulnerable.

ESWG organizers and venue managers met Monday afternoon and decided to wait and see what Wednesday brings before firming up their plans. They’ll meet again that morning.

“We know what’s coming Wednesday, and it doesn’t look good,” Caligiore said.

The weather won’t affect most of the games’ 23 sports, Caligiore said. All skating events will take place on refrigerated surfaces, from Lake Placid’s Olympic Center and Olympic Speedskating Oval to the civic centers in Tupper Lake and Saranac Lake. The bobsled-luge-skeleton track is also refrigerated.

Man-made snow stockpiled from January is expected to keep conditions usable at the games’ three alpine venues: Whiteface Mountain in Wilmington, home of alpine skiing and snowboarding; Titus Mountain in Malone, which will host big air and slopestyle; and Mount Pisgah in Saranac Lake, which is gearing up for the new sport of snow biking.

“Whiteface, Titus, Pisgah – not impacted at all,” Caligiore said. “I saw some drone photos today of the test rides at the Pisgah course – outstanding.”

Organizers got a positive report on snow at the Paul Smith’s College Visitor Interpretive Center, where snowshoe races are to be held, Caligiore said. Paul Smiths tends to be a little colder and to hold its snow longer than other parts of the Adirondacks.

The ski jumps also seem to be good to go, Caligiore said.

Conditions are not so good, however, on the cross-country trails at Mount Van Hoevenberg and Cascade ski centers near Lake Placid and Dewey Mountain in Saranac Lake.

Cross-country races could be moved from Van Hoevenberg and Dewey to Lake Placid’s ski jump complex, which has artificial snowmaking. That’s what happened to the U.S. Ski and Snowboard Association’s SuperTour races Saturday and Sunday.

“That’s not optimal because we’d like to have a bigger course,” Caligiore said, but he also pointed to a silver lining: More, shorter loops make races better for spectators.

Biathlon and ski orienteering will probably feel the heaviest impact of the weather, Caligiore said. Biathlon is supposed to be at Mount Van Hoevenberg’s specialized course. There is also a shooting range at the ski jumps, but moving both biathlon and cross-country skiing there might be tricky. Ski orienteering is supposed to be at Cascade Ski Touring Center, next to Mount Van Hoevenberg.

“Everything else is either artificial snow, artificial ice or indoors,” Caligiore said. “We’re going to keep a close eye on those nordic-type activities.”
