MADRID — A winter storm lashed much of Spain for a third day Tuesday, leaving about 200,000 people without electricity, schools closed and roads blocked by snow as it killed four people.

Massive waves and gale-force winds smashed into seafront towns, damaging many shops and restaurants.

Much of the northeastern province of Gerona was without electricity Tuesday because of a fault in the power connection with France, emergency services said on their Twitter account.

Many schools remained closed in the northeastern region of Catalonia as well as the Valencia region further south and the inland region of Aragon, Spanish media said.
