A fog advisory has been issued for parts of the Lower Mainland and will remain in effect through midday Tuesday.
Environment and Climate Change Canada (ECCC) says “near zero visibility” fog is expected to cover Metro Vancouver and east into the Fraser Valley as far as Abbotsford.

“Dense fog is expected to lift by [Tuesday] late morning.”
It says travel is expected to be hazardous as visibility could be “significantly and suddenly reduced to near zero.”
1130 NewsRadio meteorologist Michael Kuss explains that it’s imperative that drivers slow down on the roads across the region.
“It’s not just the reduced visibility that’s dangerous for driving. It’s the cold temperatures, a lot of spots are freezing or below, so the roads and the sidewalks that are untreated, with all that moisture in the atmosphere, it will be incredibly slippery,” he said Tuesday.
Drivers are advised to turn on lights and maintain a safe distance from other vehicles.
While there’s been a string of days in a row with no rain, Kuss says that the clear weather sets up perfect conditions for dense fog.
“It allows for the fog to set up as cold air descends down across the Lower Mainland, and warn air rises up over the top, creating a temperature inversion, that with low cloud, combined with cold temperatures, are making for slippery conditions on the road and incredibly reduced visibility Tuesday morning.”
Kuss explains that the fog might be more dense depending on where you are in the Lower Mainland.
“Almost all neighborhoods have at least some fog, so you may go from perfectly clear and perfectly visible to no visibility at all, and not being able to see the front of the hood of your car this morning.”
