Europe's killer storm tracks north

ABC NEWS

At least 50 people have been killed in violent storms that have caused chaos in Europe.

Most were killed in France, but Spain, Germany and Portugal have all recorded fatalities.

Packing winds just under 150 kilometres an hour, the intense low caused havoc in many countries.

Flooding was most serious in France and Spain and a 10-year-old boy was one of a number of people killed by falling trees.

In the French Vendee region, houses were inundated and people had to be rescued by helicopter from their roofs.

At least a dozen people in France remain unaccounted for and there have been at least 60 injuries.

Up to a million people were without power.

The UK is on flood alert and authorities in Denmark are on standby as the storm continues to track north.
