During the winter months, there may be periods when ice will form on the wind turbines and there is a risk of the ice falling down or being thrown off. Situations that may pose a risk of icing or ice-fall are due to either cloud-icing and / or snow-icing.
The icing forecast below show periods where there is a danger of ice building up on the turbine blade and is based on local meteorological forecasts and weather – cloud icing. Under certain conditions, however, wet snow can also settle on the wind turbines, both on the blade, tower and turbine housing. Situations with wet snow can occur at temperatures around zero degrees. If it gets colder afterwards, the wet snow can freeze and can fall off in larger pieces. Snow can also settle on the roof of the turbine housing and icicles can form on the turbine housing and pose a danger in the immediate vicinity of the turbine tower. Such cases of snow icing is NOT covered by the icing forecasts stated in the automatically updated prognosis below.
The automated warning is updated 4 times every day.
Green – No risk of cloud icing
Yellow / orange – Medium risk of cloud icing
Red – high risk of cloud icing
There may therefore be a risk of icing even when the ice-warning is green. When traveling within the recommended safety zone of 250 m, always be aware of weather conditions and risk factors and make an assessment of whether it is necessary to go close to the turbines.
• The danger increases with proximity to the turbines.
• Pay special attention when the turbines are starting up after they have stopped.
• Check the weather forecast. The risk of icing is higher with low cloud cover, when there is or has just been fog or precipitation and at temperatures around 0 degrees.
• See if you can see ice or snow on the blades or other parts of the turbine. There may also be ice on the tower itself or hanging icicles from the top of the tower.
• If you are going close to a turbine, always walk with the wind in your back.
• Never stay directly under the turbine – eat your lunch elsewhere.
