In the first half hour of the rain, the Inspectorate for Emergency Situations got 50 calls as the city sewage system couldn’t handle the huge amount of water.
Local press reported flooding in four neighborhoods: basements of several buildings, including two hospitals, were also affected.
Traffic was blocked on several streets, including the infamous passage under a viaduct which takes to Micalaca neighborhood, which gets flooded at every major rain.
The city water management company apologized for the inconvenience and added that the sewage system can handle up to 22 000 cubic meter of water a day, a quantity which formed during the two and a half hour long storm.
Locals were intrigued by the flooding, but some of them "grin and bear it".
As a sign of their creativity, shortly after the storm, modified photos of the flooded passage started to circulate of Facebook.
One of them features a wrecked ship and another picture shows the famous adventurer and television personality Bear Grylls, trying to survive in Arad.
