Doha: Qatar was hit by widespread flash flooding on Saturday as the desert state received almost a year's worth of rainfall in one day.

Roads became impassable, air traffic was disrupted and homes were flooded, while shops and universities closed.

Qatar broadcaster Al Jazeera's senior meteorologist, Steff Gaulter, tweeted that one part of the capital Doha had experienced almost a year's worth of rain on Saturday.

"Abu Hamor (a suburb) now reporting 59.8mm. (Doha average annual rainfall is 77mm.)," she wrote.

By early evening it was estimated that 61mm of rain had fallen.
