It is the second time in less than a month heavy downpours have turned roads into muddy rivers and submerged underpasses. Some drivers described frightening scenes, including Tahar Trabelsi, a Tunisian engineer living in Dakar. "There were a lot of traffic jams, we were completely blocked," he said."We weren't moving forward and - with the rain - there was a lot of water coming in - and little by little, the water was rising. So we were all blocked. "Me, when I saw that the car began to fill with water, I took the decision to get out of the car and left."
"My car was flooded 100 percent." Flooding is common in Dakar at this time of year but on Friday 126 millimetres of rain fell in just six hours. But the country's sandy roads are ill-equipped to deal with so much water and some are blaming the exceptional rainfall on global warming. Tahar Trabelsi says: "Nowadays, the intensity of the rain is huge. It's not like the rains of the past."We know about climate change, it is not complicated. "And we are next to the ocean so the flow was not the usual intensity of the rain - it was a lot of rain in a small amount of time.
