Randstad area gets entire month worth of rain in one day
Parts of the Randstad area got more rain on Wednesday than usually falls in the entire month of September. Between 40 and 70 millimeters of rain fell in Zuid-Holland, Noord-Holland and Utrecht on Tuesday, according to Weeronline. Nieuwkoop got a massive 130 mm or rain.
Usually an average of 78 millimeters of rain falls throughout the month of September, according to the weather service.
