The strongest storms for a decade in northern Spain and south-west France have wrought widespread destruction.
Winds of up to 172km/h (107mph) struck the Atlantic coast and spread inland.
More than 1.5 million homes in France were without electricity, and rail and air services were suspended in many areas.
Hundreds of technicians were deployed to try to restore power to residents but thousands of fallen trees blocked roads, hampering their efforts.
Weather agencies had forecast the storms but a wider area than anticipated was hit.
Residents in affected areas in both countries were warned to stay indoors for their own safety.
