Snow in Haines Junction, Yukon, has cancelled the 25th-annual Kluane Chilkat International Bike Relay.
The 25th-annual Kluane Chilkat International Bike Relay has been cancelled due to snow at the starting line, affecting about 1,300 riders who were set to begin the race Saturday morning.

This is the first time the race has been cancelled.

"The race was cancelled because not only snow and slush in the upper elevations in the summit legs, but right here in Haines Junction at the start," said Mike Kramer, race coordinator.


California roads still being cleared of snow in June

Crews feverishly blowing snow off the road in early June as they ready for the first summer visitors
A dangerous snow removal operation is continuing in areas of Yosemite National Park.

Snow fell as recently as Monday, but a late week heat wave with temperatures increasing by 40 degrees will help the removal of snow in the park and other areas of northern California.

Crews have been working round-the-clock through spring to clear the snow from the roads of the state's highest mountain, which stretches 400 miles.

Mountain passes are typically open by Memorial Day. Though the only road through Yosemite, Highway 120, remained closed at the park's eastern entrance this week as crews dig out from snows that topped 20 feet and drifted well over 50 feet.


Nemesis - The Sun's long-lost twin

Nemesis is apparently real, even if its bad reputation is undeserved.

For decades, some scientists have speculated that the sun has a companion whose gravitational tug periodically jostles comets out of their normal orbits, sending them careening toward Earth. The resulting impacts have caused mass extinctions, the thinking goes, which explains the putative star's nickname: Nemesis.

Now, a new study reports that almost all sun-like stars are likely born with companions, bolstering the case for the existence of Nemesis.
"We are saying, yes, there probably was a Nemesis, a long time ago," study co-author Steven Stahler, a research astronomer at the University of California, Berkeley, said in a statement.

But the new results don't paint Nemesis as a murderer: The sibling star probably broke free of the sun and melted into the Milky Way galaxy's stellar population billions of years ago, study team members said.

Climate-change expedition scrapped due to 'very severe ice conditions'

A team of scientists - aboard an icebreaker, mind you! - had to abandon their expedition because of hazardous ice conditions. Ice chunks measured 16 to 26 feet (5 to 8 m) thick. The "very icy conditions" were caused by climate change, says the group's leader.

About 40 scientists were using the icebreaker CCGS Amundsen for a 133-day expedition across the Arctic, part of a $17-million, four-year project to look at the effects of climate change. They began their trip on May 25 in Quebec City, but due to bad ice conditions off the coast of Newfoundland, the icebreaker was diverted to help ferries and fishing boats stuck in the ice. Some had even took on water.

'Very severe ice conditions'

According to the Canadian Coast Guard, the conditions were unlike anything ever seen before in the area. "It was just extreme ice conditions that required everything that we've got in order to make sure we were able to provide the services," said Julie Gascon, the coast guard's assistant commissioner for the central and Arctic region.

Record cold across Nevada - Heavy snowfall in the mountains

Several daily low temperatures and rainfall records were set yesterday across central and northern Nevada. On the same day, the state's mountainous regions received an estimated 6 - 12 inches (15 - 30 cm) of snow.

The rare winter-like storm hit parts of California and Nevada on June 11 and 12, 2017, dumping measurable snow on Lake Tahoe on the California/and Nevada border.


Winter storm in June brings up to 9 inches of snow to Idaho

Snow near Arco.
The storm that brought snow in June to East Idaho is expected to exit the region Wednesday morning but the hazardous conditions it has created on the region's waterways could continue for the remainder of the week.

The National Weather Service urges people to keep small children and pets away from East Idaho's rivers, streams and reservoirs because of the rising water levels and powerful currents caused by the storm that began hitting the region on Sunday night.

The weather service wants everyone to use extreme caution around the region's waterways until calmer waters prevail by the end of the week.

The weather service said the storm dumped several inches of snow Monday and Tuesday on many of the region's higher elevation areas — which is "highly unusual" for this time of year.

The mountains near the Pomerelle ski area received the most snow from the storm — 9 inches. The mountains near Island Park got nearly 7 inches of snow, while the higher elevations in Teton County received nearly 6 inches of snow.


Big Sky Resort in Montana sees 6 inches of snow a week before official start of summer

Big Sky Resort
A week ahead of the official start of summer, several inches of snow fell over Big Sky Resort on Tuesday. It was a sprinkling compared to the several feet that fell on this day 16 years ago.

"When I got here there was about six inches of snow on the ground and it was a bit colder," Lyndsey Owens, marketing director at Big Sky Resort, said.

It is not the first time Owens has seen June snow.

"We got 32 inches on June 13, 2001. The resort opened. They opened a gondola and two runs off of that. I was actually here and I went skiing that day," Owens said.


Unseasonably strong Spring storm brings snow to Wyoming

An unseasonably strong late Spring storm will produce significant snowfall across the Western Wyoming Mountains late tonight and into Tuesday.

Late Season Accumulating Snow Expected for Western Wyoming Late tonight and Tuesday

The low pressure center will be tracking northeast across Yellowstone Park tonight. This low will be producing numerous showers and thunderstorms this evening. Sharply colder moisture laden air will be circulating around the back side of this low as the low tracks northeast into Montana. This much colder air will lower snow levels all the way down to the valley floor at times by Tuesday morning.

Snow amounts will likely range anywhere from from 4 to 12 inches above 7500 feet along with some isolated amounts of up to 14 inches in the Tetons by Tuesday evening. 1 to 3 inches of snow is expected to accumulate in the Western Wyoming Valleys by Tuesday before melting off Tuesday afternoon.


Sierra Nevadas in California get June snow storm

Blue skies over soda Springs just after 4 p.m. Sunday gave way to light hail and then a steady dose of heavy snow for the next couple of hours.

In that time, about an inch and a half of snow stuck to cars and hillsides.

Travelers on Interstate 80 had to battle the elements on the road and the cold temperatures, which some were not expecting.

"We thought we might get some rain, even hail, but we didn't expect snow," says Tami Johnson as she headed back home to Reno.


Snow and heavy rains disrupt mining operations in desert region of northern Chile

BHP Billiton's Escondida, the world's biggest copper mine, is seen snow covered after heavy rains lashed the high altitude desert region of Antofagasta overnight and into Wednesday in northern Chile June 7, 2017.

Mines in northern Chile have suspended key operations after heavy rains lashed the high altitude desert region of Antofagasta overnight and into Wednesday, companies told Reuters.

BHP Billiton's Escondida, the world's biggest copper mine, said it was snowing and all operations had been suspended.

State-run Codelco [COBRE.UL] said mining activities at its flagship Chuquicamata deposit and at nearby Radomiro Tomic and Ministro Hales had been suspended as a preventative measure, while Antofagasta said Centinela and Zaldivar had suffered intermittent interruptions.

Polish miner KGHM's Sierra Gorda said it was considering whether to restrict some operations as a precaution.
