In addition, the city experienced 309mm of rainfall in the past 3 days. This is the largest rainfall recorded in September following 1995 when it saw more than 540mm of rainfall over the total of six days, leading to major flooding, based on the 3 days of rain accumulation flash flood-like conditions have been seen in particular during those 36-hour period of the month when the intensity of rain was at high.
