Meanwhile to the south, new evacuations were ordered Saturday evening near twin fires burning in Mendocino and Lake counties across wilderness on both sides of Clear Lake.

Two recent examples are the Carr Fire that's destroyed more than 1,000 homes in and near Redding - it's already the sixth-most destructive in state history - and the Ferguson Fire that forced the closure of part of Yosemite National Park in late July, at the height of tourist season.
Two firefighters and four other people, including two children, have also been killed in connection with the fire. "When the winds are strong enough and the fire is hot enough, sometimes, the rising air columns start to rotate".
"The Mendocino Complex fire remains a dynamic and rapidly changing challenge for firefighters, with additional evacuation orders issued on Saturday and thousands of structures remaining threatened by the massive wildfire".
Forecasters say highest threat areas include a fire near the city of Redding and the Mendocino Complex of two fires north of San Francisco.
These numbers are likely to rise further, given the Carr fire is still only 37% contained and the weather conditions will remain conducive to burns, making fighting the fire more hard.
