Good to get a headsup on these, even if the smoke doesn't reach the west coast today. If there are Canadian wildfires in Alberta or Saskatchewan this week, there will be wildfires in British Columbia by July, and that smoke will be blown south along the west coast. Makes for an uncomfortable summer if we can't open our windows to catch a breeze. Best advice is to buy the best quality furnace filters you can, and tape them over you windows to filter out as much smoke you can, while getting some air circulation on hot days.
