The KNMI issued a yellow warning on Sunday morning because of dense fog in places across parts of the Netherlands. The warning applies mainly to traffic; according to the weather institute, the fog will move northwards during the morning.
The warning was issued at 05:46 local time. The KNMI warns that visibility may fall sharply in places. As a result, motorists, cyclists and pedestrians may see one another and obstacles later than usual.
Yellow is the lightest of the three colour codes for dangerous weather. The colour means there is a risk of disruption or dangerous situations, but not that the same conditions will occur throughout the entire warning area. In fog, conditions can vary greatly between open areas, urban streets and roads near water.
According to the KNMI, the dense fog will move towards the north of the country during the morning. The warning is therefore temporary and regional. The weather institute expects conditions to improve later in the day, although patches of fog may persist in places.
Poor visibility may cause disruption to traffic. The warning is not a prediction of accidents, but indicates that the conditions require extra vigilance. Road users should adjust their speed and distance to what they can actually see.
The KNMI distinguishes between a general weather forecast and a warning. According to the KNMI, a warning is issued when the expected weather could affect society. The current warning may be adjusted during the morning if the fog clears more quickly or persists for longer.
