Stunning new photographs show the California wildfires from space, revealing just how vast the level of devastation is - as experts say it's likely to get worse as the blazes become uncontrollable in high winds.
The photos, posted on Twitter by International Space Station astronaut Randy Bresnik, show plumes of smoke covering the land and sea as the five wildfires continue to rage.
But now experts say that the high Santa Ana winds have pushed the risk level for much of Southern California into the never-before-seen 'Extreme' range.
The National Weather Service San Diego has marked hundreds of square miles - from Ojai in the north down to the Mexican border, and Ventura in the east to the 247 freeway in the west - in purple, warning of the risk of fast-growing, 'uncontrollable' fires.
That could mean the hard-won progress of firefighters on Wednesday will be erased on Thursday, as the fires - which have already put hundreds of thousands of people under evacuation orders and destroyed nearly 20 homes and buildings - grow at terrifying speeds.
