Areas in the east of Spain saw a year's worth of rainfall in under 12 hours.
The number of people killed in flash floods in Spain is now at least 205.
Rescuers are searching for survivors after a year's worth of rain arrived in one day - with the Valencia region worst-affected.
Meanwhile, a red weather alert has been issued for the south-west of the country, with more torrential rain on the way.
Rhode's Cathal Nolan who runs Ireland's Weather Channel believes an element of the flooding issues is down to human error:

Meanwhile, Alan O'Reilly, from Carlow Weather, says just half the level of rain, which led to catastrophic flooding in Spain, would have a devastating impact in Ireland.
He's calling for an early flood warning system.
Over 490 millimetres of rain fell in Valencia in eight hours on Tuesday - compared to 100 millimetres over two days last year that led to flooding in Midleton, County Cork.
Mr. O'Reilly says even double that amount would be a major disaster here:
