The Rim Fire in northeastern California continues to burn on the Stanislaus National Forest, Yosemite National Park, and the Bureau of Land Management and State responsibility land. This fire began on Aug. 17, 2013 and its cause is still currently under investigation. Over 224 square miles have been affected as of Sunday, Aug. 25. It is still only 7 percent contained. Inaccessible terrain, strong winds, and dry conditions all present at this fire make for very difficult fire fighting. The ability for this fire to create havoc spreads far and wide, beyond even the area it is consuming. Credit: NASA image courtesy Jeff Schmaltz, MODIS Rapid Response Team.

The Rim Fire in northeastern California continues to burn on the Stanislaus National Forest, Yosemite National Park, and the Bureau of Land Management and State responsibility land. This fire began on August 17, 2013 and its cause is still currently under investigation. Over 224 square miles have been affected as of Sunday, August 25. It is still only 7 percent contained. Inaccessible terrain, strong winds, and dry conditions all present at this fire make for very difficult fire fighting. The ability for this fire to create havoc spreads far and wide, beyond even the area its consuming. According to the San Jose Mercury News, "Although the Rim Fire is more than 100 miles from the Bay Area, it still could threaten San Francisco's electric supply if it damages the power system originating in O'Shaughnessy Dam at Hetch Hetchy reservoir."

The latest on the Rim Fire from inciweb.org: "The Rim incident is expected to continue to exhibit very large fire growth due to extremely dry fuels and inaccessible terrain. Rapid fire growth and extreme fire behavior and hampering suppression efforts. Aerial resources are being effective with MAFFs and VLAT DC-10 air tankers prepping locations in advance of the fires spread toward the Highway 108 corridor and along the eastern perimeter of the fire. The forecasted high winds and high potential for long range spotting however remains a significant concern for fire to advance beyond the retardant lines and allow for fire spread into the communities of Tuolumne City, Twain Harte and Long Barn to the west of the fire and east into the Hetch Hetchy watershed."

The fire itself is in control of its own weather. NBC4 in Southern California reports: "Calfornia fire officials say the fire is so large and is burning with such a force, it has created its own , making it difficult to predict which direction it will move. 'As the smoke column builds up it breaks down and collapses inside of itself, sending downdrafts and gusts that can go in any direction,'' CalFire spokesman Daniel Berlant told the Associated Press. "There's a lot of potential for this one to continue to grow.'"

Dense smoke from the fire has been a serious health threat as well. Health officials in Reno, Nevada report the air quality index in their city is in the "unhealthy" range due to the smoke fallout from the Rim Fire. The smoke has also created visibility problems for air ambulance services in the Reno area as well. The smoke has prevented them from responding to some emergency calls across the region in the last couple of days.

Fire crews have no estimate as to when the will be completely contained.
