DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z April 21, 2015

SMOKE:
Two streams of very high altitude moderately dense smoke originating
from Siberian fires (SE of Lake Baikal near the Mongolian boarder)  are
within a large area of thin smoke that covers the bulk of the continental
United States and central/western Canada.

Central/Eastern US

The main stream is centered through a polar jet that extends from Western
NW Territories, across Saskatchewan and E Alberta into W ND, E MT, SD,
NEB before turning east around the base of the trof into MO, S IL, S IN,
S OH, and Kentucky.   Additional pockets of moderate smoke can be seen
at the leading edge of the jet across central VA. Thin smoke covers much
of the Mid-Atlantic states to NC.

West US
A second stream of moderate smoke is laid out along a weak ridge across
UT, NV before being affected by SSWly flow out of the Pacific covering
much of OR and WA.  This smoke appears generally stagnant or moving
NW before moving N across WA/OR.   Thin smoke covers much of the area
between the streams including the bulk of the Rocky Mtn. Range  as far
south as N NM.

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:

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.
