A video, sent in by one of our readers, shows the black cloud eerily stationed above the city, looking very ominous.
The Journal de Montréal interviewed a meteorologist who told them he hadn't seen anything like it before. He's quoted as saying the black cloud could've been related to a rare weather phenomenon caused by dust or pollution from the ground.
It also could've been connected to a movie shoot happening at the nearby MELS Studios.
Whatever caused the black cloud, it was certainly weird. We're just glad it was seemingly harmless and not a portal to another dimension!
It's Thanksgiving weekend, also known as the only long weekend we have between now and Christmas in Quebec, and whether you're dreading your family dinner or are hoping to spend some time sleeping in, you might want to know what's open and closed in Montreal on Monday.
Lucky for you, not much will change! Here's what to expect for Thanksgiving Monday.
If you looked out the window last night, you surely noticed the immense rain and lighting taking over our city. And it seems like it may not be over just yet, as the Government of Canada is warning of the possibility for serious thunderstorms in Montreal today.
With the city currently under severe thunderstorm watch, we may be in for an intensely rainy day this Monday.
The watch is specifically in effect for the Châteauguay - La Prairie area, the Laval area, the Longueuil - Varennes area, and the Montréal Island area.
On the government's official website, we're reminded that "severe thunderstorms can produce tornadoes. Water-related activities may be unsafe due to violent and sudden gusts of wind over bodies of water. Lightning kills and injures Canadians every year."
We're also told to go inside if ever we get caught in this nasty weather. "Remember, when thunder roars, go indoors!"
