SEP 4: AQMD Smoke Advisory for LA Area Friday

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:
· the San Gabriel Mountains (Area 15);
· the WestSan GabrielValley (Area 8);
· the EastSan GabrielValley (Area 9);
· the Santa Clarita Valley (Area 13);
· the East San Fernando Valley (Area 7);
· East San Bernardino Valley (Area 35);
· East San Bernardino Mountains (Area 38).
In any area impacted by smoke: Everyone should avoid any vigorous outdoor or indoor exertion; people with respiratory or heart disease, the elderly, and children should remain indoors. Keep windows and doors closed or seek alternate shelter. Run your air conditioner if you have one. Keep the fresh air intake closed and the filter clean to prevent bringing additional smoke inside.
