The water was already knee-high on the ground floor of the hotel where Aitana Puchal had taken refuge when she received a text alert from the regional government of Valencia at 8 pm on Oct. 29 warning people to shelter in place from severe flash floods.

"We could have done with (the warning) about six hours earlier," said the 23-year-old, who had fled with other local residents and guests to the first floor of the hotel near the town of Paiporta. "We were all calming down a little from the panic and drying our feet."

Others were not so fortunate.
