Years ago I have seen some bad hail in Qatar and we had a massive rain store that turned into a mini hurricane the corniche was so flooded only one lane in the middle was passable by an SUV all the roundabouts were flooded. Due to how hard the ground is here water just sat up the top. It was a regular day and the sky became black and it rained really hard. Waves from the ocean were in the parking lot of the corniche. I have pics of a school near Al-Sadd street and their playground was a swimming pool. The wind was so hard water came in everyones homes and came in through the electric outlets. Everyhome had water come in as it forced its way into the cracks of the windows. Cars were left stranded everywhere due to the high water. Thats probably why the country is so keen to put in major drainage as to avoid what happened that day.
