DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z July 30, 2019

SMOKE:
Alaska/Canada/Eastern U.S/North Atlantic/Greenland...
Remnant smoke associated with long-range transport from Russian wildfires
could be seen stretching across the GOES-17 and GOES-16 fields of view
north of 50N. Cloud cover across much of eastern Alaska, the Yukon,
the Northwest Territory, and Ontario made smoke detection difficult in
those areas. a few larger wildfires were observed emitting dense smoke
across the northern portions of the Northwest Territories. Smoke of
predominantly light-to-moderate density covers most of the Northwest
Territories, eastern British Columbia, southern Alberta, Saskatchewan
and Manitoba, extending eastward over Ontario and southern-southeast
Quebec. The same plume is seen covering the eastern U.S. including New
England, the Mid Atlantic, and the southeastern CONUS. Most of the smoke
was moving off toward the east, with some undulations corresponding to
troughs/low pressure systems and ridges/high pressure systems throughout
the depth of the atmosphere, depending on whether the smoke has its
origins in Russia, Alaska, or northern Canada.

Oregon/Northern California/Idaho/Montana...
The Milepost 97 fire in Oregon remained active emitting thick smoke over
much of southern Oregon and far northern California with slow movement
towards the south-southeast earlier today then towards the east-southeast
in the afternoon. Remnant smoke from yesterday's Milepost 97 smoke plume
has moved east-northeastward reaching central Idaho and western Montana.

Four Corners...
The Castle fire in northern Arizona has remained active throughout
the afternoon, emitting thick smoke impacting areas north-northeast
of the fire in southern Utah. The Poison Canyon and Peavine Canyon
fires in southeastern Utah have also been producing thick smoke, which
has been traveling towards the east-southeast into far southwestern
Colorado. Remnant smoke from these fires has become incorporated into
the monsoonal high entrenched across the Four Corners region, with the
smoke covering northeastern Arizona and northwestern New Mexico.


DUST...
Texas/Western Gulf of Mexico/Bay of Campeche/Yucatan/Western Caribbean
A fairly large of area of Saharan dust covers the majority of the western
Caribbean, the Yucatan Peninsula, western Gulf of Mexico, and southeast
Texas. This area of Saharan dust has been moving around an area of high
pressure centered across the eastern Gulf of Mexico/southeastern CONUS.

Tropical Atlantic to the Leeward Islands...
A second, more expansive impulse of Saharan Dust was observed exiting
the African coast and extending/moving westward across the tropical
Atlantic today. This layer of dust was caught up in a tropical wave that
is moving towards the Windward Island...but flow around the north side
of this wave was extending the layer to the Leeward Island and areas
north of the Caribbean.

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
FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

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.
