KNMI Issues Code Yellow for Dense Morning Mist in Seven Provinces

Low visibility below 200 metres poses a traffic hazard that requires drivers to use fog lights correctly.

Overview

  • The KNMI warned of dense mist affecting Utrecht, Drenthe, Overijssel, Gelderland, Zuid-Holland, Noord-Brabant and Zeeland.
  • Dichte mist is defined by the KNMI as visibility under 200 metres, a level that can cause delays and reduced sight on roads.
  • Drivers are advised to slow down, keep larger stopping distances, use front fog lamps when visibility is under 200 metres and use rear fog lamps only when visibility falls below 50 metres.
  • Local forecasters said the mist should lift later in the day and that sunshine and mild autumn temperatures near 20–21°C are expected once conditions clear.
  • Morning radiation fog can be short-lived but locally persistent, so motorists should monitor live visibility reports and expect variable conditions across the affected provinces.
