Explanation:

The statement claims that it's not always easy to tell when a flood will occur. The text mentions that flash floods can develop quickly, sometimes in just a few minutes and without any visible signs of rain. This shows that there may be no clear indication (like visible rain) before the flood occurs, which supports the idea that predicting flood occurrence isn't always straightforward.
