Cultural Tip
In German, "wegen" traditionally requires the genitive case, which is why you see "des Sturms" instead of the more colloquial "wegen dem Sturm." In everyday speech many Germans use the dative, but in written or formal contexts the genitive is preferred. "Umplanen" is a common business‑world term and sounds natural when talking about schedules, projects or events.
