The Royal Netherlands Meteorological Institute (KNMI) has issued a code yellow weather warning for a large part of the country, effective Friday, August 21, 2026, according to Dutch news outlet NU. The alert covers the risk of thunderstorms, intense rainfall, and hail.
Regional outlets, including Omroep Brabant and Eindhovens Dagblad, report that the province of North Brabant is specifically under the warning for severe showers that could bring significant amounts of rain. The national broadcaster NOS adds that coastal provinces are also affected, and that a cyclist was seriously injured after being struck by lightning.
Additional reports from AD.nl note that the storm system may bring heavy wind gusts and that several waterspouts have already been observed at sea. The warnings are in place as a volatile weather front moves across the country, prompting authorities to advise caution for outdoor activities and travel.

The code yellow alert is the second-lowest level in the Dutch warning system, indicating that the weather poses a risk to the public, particularly for those who are less able to handle hazardous conditions. The KNMI typically issues such warnings when conditions are likely to cause disruption but are not expected to be extreme or life-threatening for the general population.
Forecasters expect the severe weather to move through the region over the course of the day. Residents and travelers are advised to monitor local updates and heed any further advisories from emergency services as the storm system progresses.
