DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 19, 2024

SMOKE:
Canada/United States/Atlantic Ocean...
A significant amount of mixed density smoke attributed to a combination
of seasonal fire activity in Canada and the United States has produced
a large mass of observable smoke. Starting from as far north as Alaska,
the smoke extended through Northeastern province of British Columbia
and then mixing with smoke from various regional wildfires. The large
mass of smoke (ranging from light to heavy density) stretched across
the northern continental plain before dispersing into the Atlantic
Ocean. Thick density smoke was mostly contained in Canada and parts of
northern U.S. As the mass moved towards the east, light to moderate
density smoke was observed dispersing down from Canada into the USA,
with moderate smoke extending as far south as Texas.

Northwest U.S. ...
Moderate smoke was produced from numerous large wildfires in Oregon
and California, where the smoke extended across California and most
of Oregon, before progressing north across Washington and Idaho. The
smoke then mixed into the larger area of moderate smoke produced from
the large wildfires in northern Canada.

AEROSOL/SMOKE:
Central-Southern Mexico/Gulf of Mexico/Yucatan Peninsula/Central
America/Cuba/Hispaniola/Pacific Ocean...
A large area of predominantly light to moderate smoke attributed to
widespread seasonal fire activity throughout central-southern Mexico,
Yucatan Peninsula, Central America and northern South America was observed
today over southern Mexico, Cuba, Hispaniola, the Gulf of Mexico, Central
America, and the Pacific Ocean off the southern coastline of Mexico,
and east over the northern Caribbean Sea. Moderate smoke was visible over
the Yucatan Peninsula and Central America. Aerosols from a composite of
volcanic emissions and industrial sources in Mexico contributed to the
expansive area of aerosol/smoke seen in these regions today.

DUST:
A moderate amount of Saharan dust was seen moving westward into the
Atlantic Ocean, a lighter amount of Saharan dust was seen moving into
the eastern Caribbean Sea toward Puerto Rico.

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

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO:

Unless otherwise indicated:

Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.

Only a general description of areas of smoke or significant smoke plumes will be analyzed.

A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.

Widespread cloudiness may prevent the detection of smoke even from significant fires.
