Overview
- The advisory covers most provinces into Saturday morning, with Reformatorisch Dagblad reporting exemptions for Limburg, Zeeland, and both North and South Holland and an expiry around 11:00.
- Visibility has dropped below 200 meters in many areas and locally under 50 meters, with Buienradar measuring about 115 meters in northern Drenthe on Friday.
- Groningen Airport Eelde suspended flights because of the fog, which also limited deployment of the Mobile Medical Team helicopters to case-by-case decisions overnight.
- Regional outlets reported differing lists of affected provinces, reflecting updates to KNMI bulletins and changing local conditions.
- KNMI urges motorists to slow down, keep extra distance, and use fog lights correctly: front fog lights when visibility is under 200 meters and rear fog lights when it is under 50 meters.
