The KNMI has issued a code yellow warning for dense fog across the northern and central parts of the Netherlands, according to De Telegraaf. The warning covers five provinces, with the northeast and middle of the country most affected, AD.nl reports. Conditions are expected to clear later, with a sunny weekend on the way.
The fog could cause problems for traffic, NU reports, describing the conditions as potentially obstructive on the roads. RTV Noord also carried the KNMI warning for dense mist in the north.
The affected provinces include those in the north and northeast, along with parts of the central Netherlands, according to AD.nl. The warning was issued on Friday morning, 2 October 2026, as the fog settled over the region.
Motorists are advised to take extra care during the morning hours while the warning remains in place. The code yellow alert is a standard KNMI measure used when weather conditions may pose a risk to road users, though it does not indicate an extreme weather event.
According to De Telegraaf, the foggy start will give way to brighter conditions, with a sunny weekend forecast for the country. The transition from low visibility to clear skies is expected as the day progresses.
The KNMI's warning system uses colour codes to communicate weather risks to the public. Code yellow, the lowest level, signals that potentially dangerous weather is expected but is not severe enough to warrant a higher alert.
Drivers in the affected provinces should monitor local traffic updates through the morning. The next development to watch is whether the KNMI lifts the fog warning as conditions improve and the expected sunshine arrives for the weekend.
