暴风雨 Rainstorm

Yesterday, it was sunny, but when it was about 5 o'clock in the afternoon, the sky turned to black. There were many dark clouds and it started to blow. After a little while, it began to thunder and lightening appeared. I was frightened. It seemed that the sky was badly angry and it wanted to punish the people in the earth. And then, it rained heavily. It looked like there was someone pouring the water in the sky. The rain lasted about fifty minutes
