The sky turned green in Sioux Falls, located in the US state of South Dakota, on July 5, when the derecho storm was effective. While the color of the sky astonished the residents of the region, the landscapes and photographs were on the agenda of the social media.
While it’s not clear why the sky turns green, experts say the main reason is that clouds tend to emit blue light because they carry a lot of water, and when blue light is combined with red and yellow light from sunset, the sky turns green.
In the statement made by the National Weather Service, it was stated that approximately 30 thousand people were left without electricity for hours in South Dakota, Minnesota and Iowa, where the derecho storm was effective. In the statement, it was stated that the storm in question had a wind speed of 93 kilometers per hour.
