Canada – Update – Fort McMurray is under evacuation for the second time in four years. The Albertan town was besieged by a huge wildfire in 2016, but now it faces flooding due to an army of ice. The Athabasca River that cuts through the town has been choked by piles of ice chunks that stretch roughly 15 miles, according to the Albertan government. That’s left water with nowhere to go but into the streets, businesses, and homes of Fort McMurray, Canada’s tar sands capital. The regional government has issued mandatory evacuation orders for 13,000 people over the past 48 hours and more could be on the way as water continues to back up on the Athabasca and other rivers in the area.

The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km-radius hazard zone from the crater.

Comet – Swan

With less air traffic due to travel bans, sky gazers have been enjoying an undisrupted view of the stars. However, stars are not the only celestial treasures worth looking up for: you may also be able to spot a pair of comets during lockdown.

South Africans should hopefully be able to catch a glimpse of the comet Swan, which is visible now and should remain visible for the next week or so, when it will move on to the northern hemisphere. As comet Swan moves closer to the horizon, it will appear to be getting considerably brighter with its tail getting slightly longer, granting an even better view.
