"The coastal area stretching from the tourist hotspots of Alicante and Benidorm in the south-east to Barcelona in the north-east, as well as the Balearic islands, have seen rainfall totals of 100-200mm (3.9-7.8in). Thunderstorms have brought hourly rainfall rates of more than 60mm, resulting in flash flooding and leading to travel chaos, including flight cancellations and stranded holidaymakers, as well as damage to property."
"Spain's state meteorological agency, Aemet, declared the extreme wet weather as being the first high-impact Dana of the autumn season. The term Dana stands for depresion aislada en niveles altos (isolated depression at high levels). A Dana is an upper-atmospheric depression, disconnected from the main airflow, potentially leading to torrential downpours, gusty winds, hail and thunderstorms. The severity of these complex systems is dependent on local conditions such as land sea temperature differences and humidity, making a forecast of their intensity difficult."
Just under a year since the 29 October floods that killed more than 230 people, major flooding again affected eastern Spain and the Balearic Islands. The coastal area from Alicante and Benidorm to Barcelona recorded 100–200mm of rain, with thunderstorms producing hourly rates over 60mm, causing flash floods, travel chaos, flight cancellations, stranded holidaymakers and property damage. Spain's meteorological agency Aemet declared the event the first high-impact Dana of the autumn. A Dana is an isolated upper-atmospheric depression capable of torrential downpours, gusts, hail and thunderstorms. Forecasting Dana intensity is difficult because severity depends on local land–sea temperature differences and humidity. Storm Alice is the first Dana given an official name by the Southwest European Storm Naming Group.
