Orange Sky in the UK

On October 16th, 2017 the sky across parts of England because of the smoke and dust from fires that occurred in southern Europe drifted north. The color came from the remains of Hurricane Ophelia and wildfires that occurred in Portugal and Spain a few days before. Smoke and sand from the Sahara desert carried north by the strong winds from the storms. The combination of events that made the sky look especially different than the UK has seen before. The smoke covered over 1,000 miles throughout the UK.
