      Yes, you can, but we need to understand the geography and geology of the area very well in order to be accurate: rivers and tidal river-mouth systems are “easy”, but flash floods inland are very difficult to predict. The best we can do is models that will tell you how high the risk of flooding is, based on the weather forecast and what we see on the area (how much pavement, how much vegetation, how hilly etc.).
