Summer and winter saw more rain. Heavy rain days decreased over time. Extreme rainfall events also decreased, happening less than 4 days per year. Significant changes in precipitation occurred in 2008, 1966, 1982, and 1959. The study predicts a gradual decrease in annual precipitation in the region, leading to drier conditions in the future.
