SMOKE:
Western/Southwestern/Central U.S. and Mexico/Pacific...
The large KNP wildfire complex in the Sequoia National Park of Southern
California has resulted in a large region of moderate to thick density
smoke. Moderate to thick density smoke was observed over a large region of
Southern California as well as offshore out over the Pacific Ocean. Light
to moderate density smoke was observed well offshore out over the
Pacific Ocean as well as over most of the Southwest U.S. including New
Mexico and Arizona as well as over Northwestern Mexico and the Gulf of
California. Moderate to thick density smoke was seen as well over most
of Nevada. Light, moderate, and thick density smoke was also seen over
parts of the Northern Rockies and over the North Central U.S. Earlier
today, moderate to heavy density smoke covered much of California and
extended northeast over most of Nevada and also traveled southwestward
approximately 540 miles over the Pacific Ocean and now has progressed
further from these regions. Several wildfires were also observed over
Central Idaho and Central/Southern Montana producing moderate to thick
density smoke progressing towards the northeast this evening.
Lower Mississippi Valley and Southeastern U.S...
Widespread agricultural burning activity was observed in the Lower
Mississippi Valley including Southeastern Missouri and Eastern

density smoke was observed over parts of the Southeastern U.S. including
Eastern Mississippi, Western Georgia, and Central/Southern Alabama
this evening.
Southwestern Gulf of Mexico/Southern Mexico...
A region of light to moderate density smoke was observed over parts of
Southern Mexico. Light to moderate density smoke from offshore drilling
platforms was also observed over parts of the Southwestern Gulf of Mexico
