I want to know the answer to the following question:
About what percentage of Kathmandu's annual rainfall falls during the monsoon months?
All the background I'm provided with is that "For example, 2003 was the wettest year ever in Kathmandu, totalling over 2,900 mm (114 in) of precipitation due to an exceptionally strong monsoon season.". Is that enough to answer the question?
Answer: no
