Disaster denied

“Southern California foothill communities escaped potentially disastrous debris flows from fire-scarred mountains during last week’s storms because total rainfall was far less than expected, the U.S. Geological Survey said Wednesday.”

Debris warning for burn areas

THE US GEOLOGICAL SURVEY today issued winter rain debris-flow warnings for communities at the feet of the San Gabriel Mountains, as well as areas in Big Tujunga Canyon, Pacoima Canyon, Arroyo Seco, West Fork of the San Gabriel River, and Devils Canyon.

If it’s any comfort to those downhill from potential torrents of debris, predictions of an El Nino for Southern California look about as promising for rainfall as another supposed El Nino year, 2006-2007, a record low

Most expenses are never assigned to the bottom-line costs of wildfire. — Comment piece in The Oregonian

By Saturday [September 19th] the arson-caused fire that claimed the lives of two firefighters was 93% contained and had cost nearly $84 million to fight. More than 700 firefighters remain on the fire lines. Los Angeles Times

Although up to 15 percent of the city of Los Angeles’ water comes from local sources such as the Angeles National Forest, other neighboring communities in the San Gabriel Valley rely on the forest watershed for most of their water. TreePeople press release

Los Angeles fires from the Earth Observatory

From top left to right, these images of the Los Angeles fires were captured on August 29th, August 30th, August 31st, September 2nd, September 3rd, September 6th and September 7th. The second to final image, taken September 6th, uses infrared definition to show the smoldering remains in black of the Los Angeles National Forest. The final one uses colorization to better define burn areas from where fire remains and unburned areas. Click twice on the image for a large version with helpful graphics overlaid.
