KATHMANDU: This year’s monsoon is expected to become active in parts of the Bagmati Province, including the Kathmandu Valley, starting today, Saturday.

According to the Weather Forecasting Division, although the monsoon has already entered the country via Koshi Province, it takes a few days to reach the Valley.

Meteorologist Saroj Pudasain explained that the arrival of the monsoon in the remaining parts of the country is delayed due to the partial influence of westerly winds and a low-pressure system centered around Bihar State in India.

The monsoon is tentatively expected to spread to western Nepal about a week after its arrival in the eastern part, but this progression has been hindered by the low-pressure system in India.

The Division reported that last night, Karnali Province and the hilly regions of Bagmati and Gandaki Provinces experienced partly to generally cloudy weather, while the rest of the provinces was partly cloudy to mainly fair.

Light to moderate thundershowers are expected in a few places in the hilly regions of Koshi, Bagmati, and Gandaki Provinces, and in one or two places in other parts of the country.
