DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z October 12, 2017
SMOKE: Napa Valley and San Francisco Bay... The intense wildfires throughout Napa Valley were seen producing moderate to thick smoke plumes extending just west of due south across the San Francisco Bay area and the Pacific Ocean. Sequoia National Forest... The Lion fire in the southern Sierra Nevada were observed producing a smoke plume of varying density throughout Sequoia National Forest. The smoke from this plume is settling into and spreading through adjacent valleys. DUST: Mojave Desert... Blowing dust was observed throughout the Mojave Desert from south-central Nevada to south-central California. Much of the dust was blowing from the north-northeast to the south-southwest. Windward Islands/Atlantic Saharan dust was seen extending from the central tropical Atlantic Ocean west towards the windward Islands. This region of dust appeared to be moving off toward the west. Hosley 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: JPEG: http://www.ospo.noaa.gov/Products/land/hms.html GIS: http://www.firedetect.noaa.gov/viewer.htm KML: http://www.ssd.noaa.gov/PS/FIRE/kml.html ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO SSDFireTeam@noaa.gov
