A huge wildfire in California's now thought to have spread even further covering over 200 square miles.
A state of emergency's been declared in San Francisco as water and electricity supplies are under threat.
The blaze is near to a key reservoir which supplies 85 percent of its water.
California's governor is Jerry Brown:
Authorities say the fires are only 20% contained.
