"Recent images of the devastating flash floods caused by Storm Daniel in Greece
hit close to home literally and figuratively. As a Greek who has completed a
PhD and worked for the past eight years on flash floods, the scenes unfolding
across my homeland are painfully real: a stark reminder of the broader
environmental challenges we face both on a local and a global scale.
These unprecedented flash floods were triggered by rainfall from the arrival of
Storm Daniel on Monday September 4 which also affected Turkey and Bulgaria. The
following day, in the village of Zagora, a record-breaking 754mm of rain fell
in just 18 hours, leaving parts of the region of Thessaly in crisis and unable
to respond.
To put this in perspective, London gets about 585mm of rain over the course of
a year while Thessaly gets 495mm, meaning that on Tuesday September 5, about
1.5 years’ worth of rain fell in 18 hours. Imagine the most torrential rain you
have ever experienced, perhaps a cloudburst lasting 20 minutes or so. Now
imagine it raining that hard but without pause for an entire day.
Flash flooding is short in duration but extremely intense, and typically
happens within six hours of heavy rainfall. Unlike regular floods, which
develop more slowly and can be predicted in advance, flash floods catch people
off guard due to their rapid onset and are rarely recorded in the field."
