Because the RMI expects inclement weather on Sunday with strong and gusty winds. In the province the wind reaches speeds of up to 70 kilometers per hour, but at sea this can be slightly more. And then, according to the RMI, lighting fireworks is really not recommended.
David Dehenauw, weatherman: “The wind speeds we predict are for a height of 10 meters. That is the standard level for which we predict wind speeds. If you let off fireworks, they will go higher than 10 meters. If you look at wind speeds at a height of 70 to 100 meters, that is even higher. So there is a danger of not knowing, especially in gusts of wind, where that arrow will land. It is difficult to determine that trajectory. If there is little wind, you know it will explode above your head and come down in the same place.”
