Calgary - Another northern Alberta oil pipeline has been shut down after operator Pembina Pipeline discovered a leak in a remote area north of Swan Hills.

An estimated 1,300 barrels were released from the underground pipeline onto muskeg and into a creek before the Calgary-based company shut down the line, said Pembina spokeswoman Shawn Davis.

"We detected a volume imbalance at our control centre and from that we initiated air and ground investigations," Davis said Wednesday. "And from there we found that there was a leak."

Toowoomba residents unfortunate enough to be caught outdoors yesterday were battered with cold winds reaching speeds of up to 56kmh.

Temperatures dropped to a low of 3.1 degrees while fresh winds brought the apparent temperature to a chilly -4.7 degrees.

Oakey had the coldest recorded temperature on the Darling Downs yesterday with a low of 1.3 degrees, although the winds were not as strong as they were in Toowoomba.

Oakey's apparent temperature reached a low of -3.7 degrees.

Toowoomba gardener Steve Ratcliffe from Rattyz Garden Maintenance said winter was a bad time to hold an outdoor job in Toowoomba.

"You never really get used to it," Mr Ratcliffe said about the cold weather. You just gotta rug up and tough it out."

Canada: Hot Humid Weather Continues in Ottawa

Road work crews in the National Capital Region are expected to finish early and vulnerable residents are being urged to seek shade as the temperature is expected to hit 34 C in Ottawa and the humidex is expected to reach 47 C.

The city's medical officer of health, Dr. Isra Levy, issued a heat warning on Wednesday, saying extreme heat can cause dehydration, heat exhaustion, heat stroke and even death. He said infants, young children, the elderly, the chronically ill, and the homeless are at greater risk from extreme heat.

The heat warning is automatically declared when Environment Canada forecasts a humidex of 40 C or more for at least two consecutive days.

The temperature was 25 C and the humidex rating was 33 C at 7 a.m. Thursday morning, but construction crews continued road work on Bank Street in the Glebe neighbourhood.

But workers are being told to take frequent breaks and drink plenty of fluids and will stop work at 1 p.m., an hour before temperatures are expected to reach their peak.

US: Massive, Deadly Heat Wave Spreads from Midwest to East Coast

The mid-Atlantic and Midwest woke up sweating on Thursday, in the clutches of a massive heat wave that has already killed at least 22 people this week and was expected to tighten its grip through the weekend.

The National Weather Service (NWS) issued excessive heat warnings for wide swaths of the country's mid-section and East Coast, saying the combination of heat and humidity could spike the heat index or "real feel" of the warmth to 115 degrees through Saturday.

By the weekend the heat was expected to cover nearly 50 percent of the country and impact nearly 50 percent of the population, according to AccuWeather.com forecaster Mary Yoon.

"What makes this heat wave so impressive is the pure size and longevity," said Yoon.

"Through the rest of this week and into the weekend at least 15 states starting from the Southern Plains and Midwest and much of the Northeast will witness 90 degree plus temperatures with high humidity."

US: In Heat Wave, Wintry States Wish for Some December

In the land of giant ice castles, where auto makers test their vehicles against extreme cold and people play hockey year-round, it's not uncommon to hear some griping about the weather.

The Upper Midwest is accustomed to extreme temperatures. Just not in the current direction.

Parts of the region are suffering through the worst heat wave in more than a decade, leaving residents who usually eagerly await a too-short summer longing for a taste of December. The heat index topped 119 degrees Tuesday in Minneapolis. And it felt like 105 degrees in Madison, Wis.

Even at the Minnesota Zoo, known for displaying northern-latitude animals, workers say the heat can make some animals - like people - "really crabby." But they're keeping thick-furred tigers happy with "bloodsicles."

"It's kind of gross, but they like it," said Diana Weinhardt, who supervises the Northern Trails exhibit. She spent 15 years at the zoo in Houston, and admitted the heat was even rough on her.

US: Alert Level Raised for Alaska Volcano

Anchorage, Alaska - The alert level for an Alaska volcano is being raised after officials say persistent thermal anomalies have been spotted in satellite data.

The Alaska Volcano Observatory on Wednesday raised the level Cleveland Volcano to advisory from unassigned.

There is no real-time seismic network at the volcano, located 939 miles southwest of Anchorage on an uninhabited island. Officials are not able to track local earthquake activity related to volcanic unrest.

Short-lived explosions with ash clouds or plumes exceeding 20,000 feet above sea level are frequent on Cleveland. It last showed signs of unrest last summer, with a small ash emission and lava flows on its upper flanks.

The observatory says the last significant eruption of the 5,676-foot volcano began in February 2001 and eventually produced a lava flow that reached the ocean.

US: Snakes Threaten Hawaii's Fragile Island Ecosystem

Long kept out of Hawaii’s paradise, snakes are increasingly slithering into the islands, posing a grave danger to tropical birds, colorful plants and the vibrant environment that draws millions of tourists to the state each year.
Hawaii has been largely successful in preventing snakes from entering the island paradise over the years and avoiding the grave danger they present to tropical birds, colorful plants and the vibrant environment that draws millions of tourists to the state each year.

But the recent capture of escaped pet snakes - illegal in Hawaii - and the infestation of Guam by brown tree snakes, which could easily make it here via cargo ship, have alarmed wildlife and agriculture officials.

Without any natural predators, authorities say it wouldn't take much for snakes to take root and multiply, potentially killing off endangered birds and flowers that make the islands special. Hawaii, home to more endangered species per square mile than anywhere else in the world, could potentially face the same fate as Guam, where brown tree snakes overran the island following World War II and wiped most birds from the skies.

"It has a high potential to be devastating to Hawaii," said Earl Campbell, assistant field supervisor for the Pacific Islands Fish and Wildlife Office within the U.S. Fish and Wildlife Service. "I would look at Guam as the template for what could happen in a range of tropical Pacific Islands that have no snakes."

Hawaii is so serious about keeping snakes out that the fine for possessing an illegal animal can reach $200,000 and up to three years in prison. But snake owners are granted amnesty if they willingly turn their pets over.

A lengthy, blistering heat wave that is blanketing the eastern half of the United States is putting significant stress on the nation's power grid as homeowners and businesses crank up their air conditioners.

Utilities say they're ready for high power demand and widespread electricity shortages or outages are unlikely. Lines and equipment are not fully taxed and there is more generating and transmission capacity available than usual because of the weak economy. Also, not many major storms are in the forecast, meaning fewer downed power lines.

The heat wave began a week ago in the Plains states and is expected to spread east through the weekend. It is lasting longer than most heat waves and is spread over an unusually wide area, according to Travis Hartman, the Energy Weather Manager at MDA Earthstat, which proves forecasts for utilities and other weather-dependent businesses.

Hartman predicts 90- to 100-degree weather from Chicago to Boston from Wednesday through the weekend. The Midwest is expected to see peak heat on Thursday while thermometers in eastern states will top out on Friday and Saturday. Philadelphia may break a 1957 record of 100 degrees on Friday, while Washington, D.C., is expected to reach 103, tying a record from 1926.
