Overview
- The KNMI issued a code yellow warning for dense mist in Groningen, Friesland, Drenthe, Overijssel and Utrecht that runs from 06:00 to 09:00 on Friday.
- Local observations recorded severely reduced visibility, with Weeronline reporting just 99 metres in Eelde and RTV Utrecht noting about 200 metres in De Bilt.
- The ANWB cautioned that additional fog banks could form elsewhere in the country, though the south is expected to remain clear.
- Forecasters say the mist should dissipate after sunrise, so disruptions are likely to be limited to the early‑morning period.
- Code yellow signals potentially dangerous conditions so drivers are advised to slow down, keep extra distance and follow regional traffic updates relayed by local media.
