THRU 0300Z JULY 04, 2005

Several fires in central Alaska northwest of Fairbanks are producing
smoke that is moving to the east and extends to the Canadian border
where it mixes with a mass of clouds.

A broad area of smoke generated over the past few days from the fires
in Alaska and the Yukon Territory is mixing with smoke from fires now
seen over northern Saskatchewan and Manitoba. This thick area of smoke
extends from Great Slave Lake in the Northwest Territories southeastward
across northeast Alberta and northern Saskatchewan, covering Lake
Athabasca, and into northwest Manitoba. The smoke is thickest across
Alberta and western Saskatchewan and the whole mass is generally rotating
anticyclonically with the northern edge being drawn further north ahead
of a frontal system.

The most intense fire this evening producing the thickest and most
extensive smoke plume is the complex burning over southeast Nevada. The
smoke from this fire extends east and southeast into central Arizona
and reaches nearly to the Four Corners area. The blazes over central
(Cave Creek), southwest (east of Gila Bend in the Maricopa Mts) and
northwest Arizona (near Grand Canyon) are producing lesser plumes of
smoke that are mainly moving to the east-northeast. A cluster of fires
over southwest New Mexico in the Gila and Apache-Sitgraeves National
Forests are producing smoke plumes extending eastward across the state.

A fire in the Okanogan national forest near Winthrop is producing a
smoke plume extending to the east and southeast.



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.
