Weather can change plans in minutes: a clear morning turns foggy, or a light breeze becomes a hard gust by dismissal time. Leaders who prepare well look beyond today’s forecast and study patterns that repeat across years. Reading a historical weather report adds context to short-term updates, showing how a place usually behaves in certain months, at certain hours, and under certain winds.

Historic rainfall is one of the most striking examples of how nature frequently reminds us of its power in unexpected ways. Overnight changes can occur in cities, towns, and landscapes when storms release more water than ever before. These incidents demonstrate the vulnerability of our systems to uncontrollable forces.
