The information is supplied by Europe's leading national weather services, and covers the most popular business and tourist destinations. The web site uses recognisable, universal images to avoid any potential language barriers and is clear and easy to use. It uses a traffic light system on a geographical map of Europe to indicate where severe weather is expected. A range of potential weather and environmental elements are covered including heavy rain, strong wind, high and low temperatures, snow and ice, and avalanches.
