DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z April 18, 2012

Mid-Atlantic:
Thin density remnant smoke could be seen drifting off the Mid-Atlantic
coast of the US. It was tracking southeastward ahead of a surface cold
frontal boundary.  This area of remnant smoke is the result of numerous
fires in the eastern US over the past few days.

Gulf of Mexico:
A relatively small area of detached thin density smoke from fires burning
across Cuba is tracking slowly northward across the southeastern region
of the Gulf of Mexico.

Northwest Mexico:
Remnant and recently detached smoke plumes are seen across portions of
northern  Mexico this evening.  Smoke plume extends across the Mexico
states of southern Sonora, southwestern Chihuahua, Sinaloa, and western
Durango. Fires burning in the Mexican states of Durango, Sinaloa and
Chihuahua are believed to be the source of this smoke, which is drifting
slowly north and west.

Great Lakes:
Unknown aerosol could still be seen in GOES-EAST imagery stretching across
the Central Great Lakes region. Based on the analysis from this morning,
it is likely that this area of aerosols still extends south and west
across the Central Plains. Due to the warming land surface temperatures
it is more difficult to detect this area of aerosols over land, but the
cooler surface lake temperatures make identifying this aerosol plume much
easier. It is possible that aerosols are the remnants of the large blowing
dust event that occurred over the southwest U.S. this past weekend that
has now become elevated.

Southwest U.S.:
Area of unknown aerosol was seen drifting east-southeast across southern
California northern Baja is evening GOES-EAST satellite imagery.
It's possible that aerosol may be dust from Asia that tracked across
the Pacific.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT
AREAS 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.
