Monsoon to remain weak for four days, says MFD

Kathmandu, June 20

The Meteorological Forecasting Division today said monsoon would remain weak for the next three days or four due to dominant westerly winds.

According to the MFD, the mid and western plains will record higher temperatures during the period.

“Most parts of the country have not witnessed rainfall for the past few days as a result of strong westerly winds. The impact of monsoon trough is likely to gradually increase across the country after the westerly winds fizzle out,” it informed.

The MFD had officially declared the onset of monsoon in Nepal on June 8, two days ahead of the normal date. This marks the arrival of the rainy season in the country. Monsoon usually enters Nepal on June 10 and withdraws on September 23 every year. It may take a few days for the active monsoon trough to spread across the country bringing plenty of rain, MFD said.

Once monsoon enters from the eastern region, it makes progressive westward advancement to the remaining parts of the country over the next few days through the central region, but the strong westerly winds have resulted in low rainfall.

Monsoon lasts for an average of 105 days. Nepal receives an average of 80 per cent annual rainfall during the monsoon, which originates in the Bay of Bengal and moves along the southern flanks of the Himalayas. The average annual rainfall in Nepal is 1,600 mm, but it varies from place to place depending on climatic conditions.
