The KNMI has declared code red for the whole country for Sunday. This is associated with poor visibility, cutting cold and the likelihood of formation of “traffic barriers” snow dunes.
Due to the strong east wind, there is a snow hunt. As a result, snow dunes can be created that pose dangerous situations for traffic. In addition, the visibility in the snow is poor, possibly less than 500 meters, and it is cold to the feeling.
Most wind is in the northern half of the country. In the coastal areas there and above the IJsselmeer, heavy gusts of wind up to 90 kilometers per hour occur.
It is also going to snow quite a bit from Saturday evening. Most places in the Netherlands will fall about 10 centimetres, but in the east and middle of the country the snow cover can become much thicker. Locally there can fall between 15 and 30 centimeters of snow, predicts Weer.nl. On December 11 in Hoog-Soeren on the Veluwe there was a layer of 44 centimeters and code red was also issued. The snow record still dates back to 1987. In January of that year Terschelling fell no less than 80 centimeters.

Because of the extreme weather conditions, the KNMI has now proclaimed code red. This happened for the last time on 31 December 2019 because of very dense fog in the provinces of Friesland, Groningen and Drenthe. The last time the whole country had to deal with code red was on February 13, 2012, because of freezing rain and ice rain.
Code red means ‘take action’
The KNMI works with various colour codes and these are international warning colours. For all weather types – precipitation, temperature, wind, thunderstorms – code yellow, orange and red can be issued. Code red means: take action, as it says on the site.
“ This is a weather alarm in which extreme weather has a major impact on society. The weather situation can cause so much damage, injury and nuisance that it can be socially disruptive. This could be very local. Code red is issued at the earliest 12 hours before the weather phenomenon occurs. Code red can also be issued if there is a small chance of an extreme weather situation, but the safety risks are high.”
Code green means: no particulars. With code yellow it is recommended to be alert because there is a possibility of dangerous weather. With code orange, there is a high risk of dangerous or extreme weather where the impact is high and there is a risk of damage, injury or a lot of nuisance. This could be very local.
