With record-high Mediterranean temperatures and a year's worth of rain falling in mere hours, Spain has been devastated by the weather phenomenon known as DANA.

Climate scientists and meteorologists say the immediate cause of the flooding in Spain is a DANA, a cut-off lower pressure storm system that migrated from an unusually wavy and stalled jet stream.

Parts of eastern and southern Spain are now dealing with the aftermath of historic and deadly flooding at the hands of a storm system that brought incredible amounts of rain in short order.
