SMOKE ADVISORY Friday, September 04, 2009
Smoke from the Station Fire in the Angeles National Forest continues to cause poor air quality at times in portions of the San Gabriel Mountains (Area 15) and the San Gabriel Valley (especially Areas 8 and 9). High concentrations of fine particulates will occur in areas of direct smoke impacts near the fire, especially in the foothill communities. Control of the Oak Glen and Pendleton Fires near Yucaipa has been substantial, although some areas of smoke may still occur.
While fire control and meteorological conditions have improved air quality, some smoke has settled into the valleys of Los Angeles County overnight near the fires. Onshore ocean breezes by the afternoon are expected to move smoke into the mountains. Prior to the onshore flow clearing the western Basin, smoke will linger in areas of Los AngelesCounty and in the eastern San BernardinoValley near the fires.
Air quality will reach Unhealthy levels, or higher, in smoke impacted areas, especially near the fires. These areas will likely include:
