Four people have died in Spain after powerful storms swept across the country's east. In the Valencia region, authorities ordered 145 municipalities into temporary confinement while the rain kept falling. Rescue helicopters were sent up to reach communities cut off by floodwater. Emergency agencies are tracking the system as it pushes toward the Catalan coast, where new warnings are possible. Storms of this kind, fed by warm Mediterranean water, are a recurring autumn danger along Spain's eastern seaboard. Officials have not ruled out raising the death toll as access improves to the hardest-hit areas. For now, crews remain on standby and residents in exposed towns have been told to stay indoors until the alert is lifted.
