homes in Wainfleet evacuated and nearly 130 properties flooded when the River Steeping burst its banks. There were also flooding problems across parts of east Wales with transport links affected. Weather data The analysis charts below show a north-easterly airflow affecting the UK, with a slow-moving

centuries later. Throughout the ages, thinkers, philosophers and naturalists examined the phenomenon of the rainbow effect, noting its appearance not just in the sky but in other circumstances too. But in every case, two elements were essential for that characteristic burst of colour, water vapour

an indication of expected cloud conditions and temperature. Finally it would highlight any weather-related hazards that were likely to occur in particular counties or districts. These would include violent thunderstorms, high winds, unusually high or low temperatures, floods, flash floods and landslides

What are clouds? Overview What are clouds? How do they form? In this activity you’ll learn the answers to these questions and find out how to identify clouds. You’ll then get the opportunity to make your own cloud spotting binoculars, and watch the clouds go by, by going outside or looking out

differences, and some very high resolution climate modelling suggests that summers may tend to become drier overall but when it does rain it will fall in heavier bursts, which has implications for flash flooding. • Drought - It is very challenging to say whether drought events are becoming more common
