Overview
- The KNMI issued code geel for Thursday night covering Zuid‑Holland, Noord‑Holland, Utrecht, Flevoland, Gelderland, Zeeland, Noord‑Brabant and Limburg and set the alert window roughly from 22:00 to 03:00.
- Forecasters warned of heavy bursts of rain that can cause local wateroverlast, hail up to about 2 cm in diameter, and wind gusts of 60–75 km/h that may break branches or topple trees.
- Meteorologists stressed substantial uncertainty about how severe the storms will be and said heavier cells could pass elsewhere while some areas still face intense, localized downpours.
- KNMI recently added a location‑based, near‑real‑time thunderstorm alert to its app and that feature could be used for the first time during this event if users update the app and enable notifications.
- Organisers have already changed or cancelled exposed activities such as rooftop events, and KNMI flagged a possible separate code geel window for Friday afternoon (about 14:00–19:00), so people should monitor updates and secure outdoor items.
