Overview
- The KNMI has issued code yellow for the west coast of South Holland, which covers Friday morning and warns of wind gusts of about 75–90 km/h that may affect roads and outdoor activities.
- The institute advises people to secure loose items, keep windows and doors closed, drive more slowly and keep extra distance from other vehicles.
- Damage and disruption were already reported during the warning period, including fallen trees, broken branches, a roof sheet blown off and traffic delays on the A4.
- KNMI applies code yellow when gusts reach about 75 km/h (with a higher 90 km/h coastal threshold in the winterhalfjaar) and issues province-wide alerts to inform the public and allow emergency services to scale up.
- The KNMI is piloting an app to send highly localized, short-notice push alerts (for example about 15 minutes before a passing shower) to reduce broad warnings and improve public response.
