According to Environment Canada's, Brian Proctor, the fog is a good thing for the valley and surrounding areas.
"We've been warming up nicely and that bright sunshine has been able to melt some snowfall on the ground." Proctor continues, "With that low level moisture, the temperatures fall over night and that tends to form fog."
Even though the temperatures are warming, we are still expecting a few more snowfalls before spring is in full swing, such as this weekend. This is going to increase the fog in surrounding areas.
"It's more to the northern edge of most of the snowfall that's coming through, but again, we are going to increase that snow-pack which is going to perpetuate that fog problem over the weekend and moving into next week. " Proctor said.
The air-quality is unaffected by the fog as it isn't a form of smog in ways that we see in bigger cities.
"We are seeing a lot of fog and a little bit of industrial particles that help that fog to form and extend a little bit further." Proctor explained, "But more then that, we aren't seeing in any way any significant impact on the air-quality. We aren't seeing a lot of smoke of that nature at this time."
The fog is being caused by warming temperatures, which means reduced visibility when traveling on roads and highways. Please be advised to drive safe and stay alert in situations with heavy fog or bad weather.
