the Flood This is about the flood occurred in my hometown this week. The weather hasn't been stable over the past few days. Intermittent afternoon showers had kept me from going out for days. One afternoon, I really had to go downtown and run some errands. Even though I saw the clouds were getting darker and darker, I got on my motorbike and started the engine. As soon as I got in the library, it started to pour. The rain kept lashing against the window panes, and I found myself trapped in the building. After checking out the books, I decided to go home right away. I missed my comfy home and was a bit worried about the restless heavy rain. On my way home, many streets were badly flooded. Some roads were blocked, and a man even waded across the water with his son on his back. The situation was worse when I got home. My community was such a mess. The water had receded. All I could see everywhere were the muddy roads, debris, twigs, and garbage washed down from the hills. My mum was cleaning the porch with a hose. I felt sorry for leaving her alone at home. She told me that she was pretty nervous when the murky floodwater crept up the road. We hadn't seen flood for years after the improvement of the drainage system. Good thing that the water didn't really flood into our house, compared to my neighbors, whose house were badly damaged. Many works needed to be done to get things back to normal. And the head of the district told us that, all the households in my community are qualified for property tax exemption this year. What good news! -- please help me with some sentences to describe flood or downpour, thanks
