THROUGH 1730Z September 22, 2006

Update for Northern and Central California:
Gusty northerly winds fanned new fires which popped up overnight in
Yolo County as well as Napa County of north central California. A
closer examination of morning visible imagery did show an area of
relatively thin smoke primarily from the Yolo County fire which had
spread southward through the Sacramento Valley and San Joaquin Valley
reaching a point southwest of Fresno as of 1730Z. Surface observations
from Lemoore(KNLC) indicated a reduction in visibility due to smoke. A
newly formed narrow smoke plume was also observed with the Napa County
fire which was moving in a southwestward direction and into portions of
the Oakland/San Francisco Bay region.

Southern California/Arizona/New Mexico/Texas/northern Mexico:
The enormous Ventura County fires continue to burn today and are still
produce smoke plumes, but the coverage over the coastal portions of
southern California including the Los Angeles and San Diego metro areas
cannot be determined due to low clouds associated with the marine
layer which have moved into southern California. However, additional
smoke which originated mainly from yesterday's flare up can be seen
moving to the south and east from this morning's satellite imagery. The
thin to moderately dense smoke covers a large area including interior
southern California, the southern half of Arizona, southern New Mexico,
far western Texas (around El Paso), and northern Mexico.

Northern California:
Moderately dense to locally dense smoke from the Trinity County fires
is observed moving in a southwesterly and southerly direction and well
out over the Pacific this morning. The fire in Sierra County continues to
burn and produce a narrow plume extending to the west-southwest  reaching
to the border between Sierra and Yuba counties.



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.
