Overview
- The fog formed Thursday evening and prompted a KNMI code yellow for dense mist that covered much of the country during the Friday morning rush, with visibility often under 200 metres and locally under 50 metres.
- The low visibility made driving hazardous and authorities advised using front fog lights while keeping rear fog lights off unless sight falls below 50 metres to avoid dazzling following traffic.
- Eindhoven Airport reported dozens of delays and two cancellations as low visibility prevented some landings, a problem worsened by its higher landing minima of about 550 metres compared with Schiphol’s roughly 75 metres.
- By Friday afternoon the worst of the fog had lifted in many places but persistent low cloud and regional greyness remained, and pockets of mist were still possible into Saturday.
- Forecasters say the same calm winds and cooler nights that formed this episode could produce renewed night fog and a later risk of ground frost, which may cause further travel disruption and require caution for drivers and farmers.
