SMOKE:
Area from Oregon and California eastward over the Northern and Central
U.S. and Southeastern Canada...
A large area of very thin density leftover smoke from the Western
U.S. wildfires was noted covering a good portion of the Northern and
Central U.S. from Montana and Wyoming eastward to the Great Lakes Region
and southward from there over the Mid-Mississippi Valley and Central
and Southern Plains. Farther to the west, more significant smoke was
seen across southern Oregon, northern California, northwestern Nevada,
and southwestern Idaho. The thickest smoke was visible over southwestern
Oregon and northern California closer to the larger wildfires in that
region. In the area covering northern Nevada, southern Idaho, northern
Utah, and western Wyoming, it was difficult to distinguish between smoke
and blowing dust(see below).
DUST:
Northern Nevada/Southern Idaho/Northern Utah/Western Wyoming...
Blowing dust originated from many point sources in northwestern and
northern Nevada as well as southern Idaho and possibly northwestern Utah
resulting in a sizable swath of dust which spread over northern Nevada,
southern Idaho, northern Utah, and possibly into the western part of
Wyoming though it is difficult to differentiate between the dust and
smoke from the Western U.S. wildfires. The thickest dust appeared to
originate again from the Carson Sink in northwestern Nevada and from
another dry lake bed in Churchill County of west central Nevada.
Northern Baja...
Similar to last night, blowing dust emanated from a source in northern
Baja and fanned out as it moved to the north in the general direction
of the southern California-Mexico border.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS OF
SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME DETACHED
FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE.
TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST ARE
ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF THESE
AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO THE SOURCE
