Why Is Predicting Hyperlocal Rainfall Challenging?

According to meteorological experts, hyperlocal rainfall is difficult to forecast due to its dependence on complex factors like upper-air cyclonic circulations, moisture transport, and wind convergence. These conditions can lead to the rapid formation of deep convective clouds, resulting in intense rainfall. Predicting the exact location and intensity of such events remains a significant challenge for weather forecasting agencies.
