Smoke from Canadian wildfires that has descended upon parts of the eastern US and Canada in a thick haze has drifted over Norway and is expected to hit southern Europe, Norwegian officials said on Friday.
Using a climate forecast model, atmosphere and climate scientists with the Norwegian climate and environmental research institute (NILU) predicted how the smoke would travel through the atmosphere, flowing over the Scandinavian country before moving further south. The smoke was not expected to pose a health risk there.
"Smoke from the forest fires in Canada is still drifting in over Norway. It will also reach other parts of Europe over the next few days," the institute said on Twitter.

The Donnie Creek fire has grown in size yet again.
According to the B.C. Wildfire, the fire is bigger than all of the fires that burned in B.C. last summer combined. It is 168,395 hectares, an increase from yesterday's size of 157,500 hectares.
The weather is contributing to fire activity. The clouds are decreasing the fire activity since yesterday compared to the erratic activity from the weekend. However, the fire is pushing southeast due to winds from the west.
"We are looking at warmer temperatures tomorrow and full sun. No precipitation coming either. And, the relative humidity is dropping and that just means the air is getting drier around the fires," explains B.C. Wildfire's Information Officer Bryan Zandberg.
