Lower Mainland under another fog advisory

A fog advisory has been issued for parts of the Lower Mainland for the second time in as many days.

Once again, Environment and Climate Change Canada (ECCC) says “near zero visibility” fog is expected to cover Metro Vancouver, including Vancouver, Burnaby, and New Westminster through Thursday midday.

“A ridge of high pressure over southern B.C. is creating favourable conditions for dense fog development. Fog remains dense for areas near the Strait of Georgia and low-lying areas,” said ECCC.

“Fog will redevelop [Wednesday] evening in areas that have cleared out [Wednesday] afternoon.”

In heavy fog conditions, 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.

While there’s been several 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.”

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”

Drivers are advised to turn on lights and maintain a safe distance from other vehicles.
