DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0115Z June 04, 2014

SMOKE:
Canada:
Thin to moderately dense residual smoke associated with the larger
wildfire complexes in Alaska over the last week or so, can be seen across
N Canada, with two distinct bands converging to an apex over the SW
portions of Hudson Bay.  The southern arm is laid out E-W over N Manitoba
to S Reindeer Lake into N Saskatchewan.  The second is oriented ESE- WNW
from far NW Manitoba, across SW Nunavut into Central NW Territories.
Each are around 100km wide with a gap of about 100km between them
on average.

DUST:
Wyoming/Colorado/Nebraska:
A thin line of light blowing dust was seen dropping south across extreme
southeast Wyoming and western Nebraska and into northeast Colorado late
this afternoon and evening. This dust was generated from gusty winds
associated with the outflow from a cluster of strong thunderstorms that
moved eastward across the region.

VOLCANIC ASH:
Alaskan Peninsula:
The eruption of Pavlof volcano in the Alaskan Peninsula is producing ash
that can be tracked on the Anchroage VAAC webpage or via header FVAK21
PAWU through the Global Telecommunications System (GTS).     This ash
is generally moving SW and NW from the volcano... however a vog or haze
could be seen east of the volcano into the Gulf of Alaska, just north
of a significant confluence zone from deep southerly flow converging
with N or NE flow from a cyclone dropping SSE along the Alaska coastline.

Earlier Analysis:
Southern/Central Plains:
An area of remnant smoke/haze has shifted north from yesterday stretching
from eastern Colorado, southern Nebraska, Kansas, western Missouri and
northeastern Oklahoma.  Most of the smoke that remains mixed with the
haze/pollutants is believed to have originated from wildfires in Arizona.
Additionally, a second area of aerosols that may include dust/smoke
is observed across south-central Canada across the Northern/Central
Plains and reaching the central Great Lakes region.  Dust transported
from Asia may be mixing in with some smoke from a clustering of fires
burning across central Saskatchewan.

Northern Canada:
Residual area of smoke extends across portions of southern Northwest
Territories, Nunavut, northern Saskatchewan and northern Manitoba.
It is believed that smoke may have originated from wildfires that had
previously existing in Alaska.

Mexico:
Area of remnant smoke associated with several large wildfires burning
across the southeastern Sonora/western Chihuahua states of Mexico is
moving west-southwest.

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.
