A storm in Spain killed four people, paralyzed travel and blanketed the capital Madrid in so much snow on Saturday that skiers took to the main Gran Via thoroughfare.
Forecasters warned of more havoc next week after Storm Filomena brought the heaviest snowfall in decades across central Spain.
In the Madrid area, rescuers reached 1,500 people trapped in cars, while on the usually traffic-clogged Gran Via, residents snowboarded and pelted each other with snowballs as well as ski.

Between 20-30 cm of snow fell in Madrid, making it the heaviest there since 1971, he added.
The capital's Barajas airport was shut from Friday night, while nationwide, more than 650 roads were blocked.
