Rainfall Amounts

The only figure available for the time of the floods is from Antofagasta, which saw 24.4 mm of rain fall in 24 hours between 25 and 26 March 2015. The relatively small amount (compared to other major flood events) is the equivalent of 7 years of rainfall in this desert region.

Causes of the Floods

The causes of the heavy rainfall have been mentioned here. Warmer sea temperatures (attributed to El Niño) combined with an unusually strong and persistent “cut-off” low pressure system that was trapped over Chile by an exceptionally strong ridge of high pressure, resulted in unusually heavy rainfall, according to RMS.

Heavier than normal rainfall falling on dry desert land and rocks, on steep mountainsides with little soil or vegetation, resulted in torrential runoff, which, by the time it had reached coastal areas such as Taltal and Chañaral, had become a raging torrent.
