Netherlands saw 188,000 lightning discharges this weekend; KNMI calls it exceptional
A storm system that developed after the recent heat produced more than 188,000 lightning discharges across the Netherlands, a level the Royal Netherlands Meteorological Institute (KNMI) described as exceptional in its records. The storms have resulted in one death, as well as multiple fires.
The KNMI said its lightning archive shows only a few recent storms have exceeded 100,000 discharges. A spokesperson told NOS, “The energy in the air was exceptionally high.”
The institute stated that it cannot link the storm strength directly to climate change. It said trends in thunderstorms, hail, and wind gusts are “much more uncertain than previously thought.” The agency added that there is no clear basis yet to say whether lightning will increase in the Netherlands.
It did, however, confirm an increase in heavy rainfall days. In the second half of the 20th century, the Netherlands averaged about five per year. In this century, that is about nine per year. KNMI expects this trend to continue, especially in summer.
The institute said thunderstorms need three ingredients: “Moisture, an unstable atmosphere, and something that makes the air rise,” meaning a lifting trigger such as a front, terrain, or surface heating. Warm, moist air rising and mixing with colder air can form storm clouds. As air rises and cools, electrical charge builds until lightning forms.
Multiple incidents occurred during the night of Friday into Saturday. A young woman was killed when a tree struck a car. A house caught fire after a lightning strike and a wedding celebration was swept away by flooding.
In Waalwijk, during the night of Saturday into Sunday, lightning struck a home at about 3:10 a.m. on Sint-Antoniusstraat, causing a major fire. The blaze spread quickly through the upper floor. Fire crews from Waalwijk and Sprang-Capelle responded with two fire engines and an aerial ladder truck, later supported by additional units. By the time firefighters arrived, the fire had already expanded.
The house was heavily damaged and declared uninhabitable. Firefighters continued work for hours, removing roof tiles and putting out hotspots. Nearby homes were evacuated as a precaution while residents waited outside in storm conditions.
The Dutch Safety Board warned earlier this year that the Netherlands is not fully prepared for risks from extreme rainfall and urged better early warnings and wider sharing of groundwater and stress-test data.
Hot weather is expected to continue, with temperatures up to 32 degrees Celsius. A code yellow warning remains in place through Tuesday, with more thunderstorms possible in the south.
