#StormAusten, 23 October: five places where the press reported fallen trees (Brussels, Etterbeek, Anderlecht, Schaerbeek, Molenbeek). CLARA's wind model flagged all five that day at alert or higher tree hazard level. On forecasts, it shows in advance where accidents are most likely. #ExtremeWeather

Storm Austen hits Belgium on Friday, gusts of 80 to 100 km/h. In Brussels it depends on your street: towers, corners and wide boulevards speed the wind up, a few metres from calm streets. The free CLARA app shows the wind at pedestrian level, street by street: www.clara.city
