... Smoke infiltrating parts of western Washington today and
becoming more widespread tonight into Sunday morning...

Wildfires on Vancouver Island producing low level smoke has
drifted southeast, infiltrating parts of Clallam and Jefferson
counties. Air quality for sensitive groups is occurring and should
be expected today with a period of slight improvement later today
or tonight as the flow switches offshore. This will eventually
worsen air quality along the Strait and other areas of Clallam
and Jefferson counties by Sunday morning. Air quality will likely
deteriorate further to unhealthy levels Sunday through Tuesday.

Smoke from British Columbia wildfires can be seen on visible
satellite imagery moving into the north and central Cascades, and
north interior from the northeast. Elevated smoke will likely
increase today over other parts of western Washington. This smoke
will gradually mix down and start to affect air quality at the
surface in the north interior, olympic peninsula, and Cascades
Sunday morning. Air quality will likely deteriorate over most
remaining areas of western Washington Sunday afternoon into early
next week. An air quality alert may be issued later today for the
Sunday to Tuesday time period. Continue to monitor forecasts as
updates are likely today.

Temperatures on Monday and Tuesday will be in the 80s to low 90s.
A marine push developing Wednesday may begin to improve air
quality to some degree.
