The strongest storms for a decade in northern Spain and south-west France have brought chaos to the area.
The storms are thought to have claimed five lives in Spain, as winds of up to 107mph (172kmph) struck the Atlantic coast and spread inland.
More than one million homes in France are without electricity, and rail and air services have been suspended in many areas.
Hundreds of technicians have been sent out to to try and restore power to homes in the area, but thousands of fallen trees have blocked roads, hampering their efforts.
Weather forecasters had predicted the storms but they ended up hitting a wider area than was thought.
People living in affected areas in both countries have been warned to stay indoors for their own safety.
