In August 2005 there were two such heavy storms that created havoc, the first occurred on August 2, 2005 and is thought to have a played a contributing factor in the Air France Airbus crash landing into a ravine that afternoon. The second happened on the afternoon of August 19, 2005 in what has been described as a "once in a hundred year" event, up to 183mm (over 7") of rain fell in parts of the northern end of the city in under a couple of hours. Numerous roadways and bridges were washed out and insurance claims from backed up sewers and flood damage has exceeded $400 million.
