DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z May 2, 2013

Eastern Pacific/Northwest US/Southwestern and South Central Canada:
An extensive area of aerosol covers the eastern Pacific off the western US
coast and stretches northeastward across northern California, the Pacific
Northwest, northern Idaho, Montana, northwest North Dakota, southeast
British Columbia, Alberta, Saskatchewan, and southern Manitoba. The
bulk of this aerosol is believed to elevated dust that was transported
from Asia though smoke from active fires in northern California, Oregon,
and northeast Washington was also contributing to the aerosol mixture.

Midwest/Ohio Valley/Great Lakes/Southeast Canada:
Another large area of aerosol thought to consist of dust (possibly from
Asia) and pollutants could be seen from northeast Missouri/east Iowa
northeastward across Lake Michigan to east Ontario/southwest Quebec and
eastward across the Ohio Valley/Michigan/Lake Huron. The aerosol mixture
appeared most optically thick over southern Wisconsin, Lake Michigan,
and western/northern Michigan.

Central Oklahoma/Texas/Northwest Gulf of Mexico/New Mexico/Southwest
Colorado/Arizona/south Utah/South Nevada:
A strong cold front dropping southward through northwest Texas today and
another frontal boundary across Arizona/New Mexico were causing strong
surface winds that had kicked up quite a bit of blowing dust/sand by this
evening. A thinner area of possibly day old/more elevated dust could be
seen over central Oklahoma southward over the eastern half of Texas and
the northwest Gulf of Mexico. Thicker dust was seen over southwest/west
Texas, much of New Mexico, southwest Colorado, southern Utah, Arizona,
and southern Nevada...mostly moving southward.

Gulf of Mexico:
A large area of thin to moderately dense smoke covers much of the Gulf
of Mexico as numerous fires in Central America and Mexico continue to
burn. The smoke stretched to just south of Louisiana where it became
obscured by thick clouds.

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.
