The Royal Netherlands Meteorological Institute (KNMI) has issued a code yellow warning for the entire province of North Holland due to dense fog expected to persist until 8:00 AM tomorrow, March 9, 2026. This follows a morning of similarly poor visibility caused by the fog, which is anticipated to cause traffic disruptions and potential delays for both road and public transport users. The KNMI advises drivers to reduce speed and use appropriate lighting, specifically fog lights at the front for visibility under 200 meters and at the rear for visibility under 50 meters. The code yellow is set to expire at 8:00 AM, with the fog expected to dissipate, giving way to sunshine and a temperature of thirteen degrees Celsius.
