Kathmandu, October 10
Low pressure trough oscillating between Bihar and West Bengal of India for the last two weeks has delayed monsoon withdrawal from Nepal.
According to Meteorological Forecasting Division, although monsoon has already withdrawn from the western part of the country, it has yet to retreat from central and eastern parts.
Meteorologist Sanjaya Shrestha at MFD said monsoon would completely retreat from Nepal only after the trough moves away from Uttar Pradesh. “Low pressure trough is unlikely to become inactive for at least four to five days. Hence, monsoon will retreat from Nepal only after October 15,” Shrestha told The Himalayan Times.
Shrestha said central and eastern parts of the country are likely to receive rainfall for the next three days. “Light to moderate rainfall is likely to occur at several places of central and eastern regions for the next three days,” he added.
Although the government has yet to prepare monsoon evaluation report, many places of country have received mixed rainfall since the onset of monsoon on June 12 this year.
According to monsoon monitoring report 2017 of Department of Hydrology and Meteorology , Taplejung received 87 per cent rainfall, Biratnagar 83 per cent, Dharan 100 per cent, Dhankuta 73 per cent, Okhaldhunga 74 per cent, Janakpur 73 per cent, Jiri 108 per cent, Kathmandu 71 per cent, Simara 93 per cent, Lumle 86 per cent, Pokhara 87 per cent, Bhairahawa 101 per cent, Jomsom 118 per cent, Dang 100 per cent, Nepalgunj 89 per cent, Surkhet 84 per cent, Jumla 102 per cent, Dhangadhi 87 per cent, Dipayal 78 per cent and Dadeldhura 93 per cent till the end of September.
This year monsoon entered Nepal on June 12 after a delay of two days. Monsoon normally arrives in Nepal on June 10 every year.
According to DoHM, last year’s delayed withdrawn of monsoon become the fourth most delayed monsoon ever. Apart from monsoon this year, the year 2013 saw the largest deviation from the set monsoon withdrawal period, ending that year on October 19 instead of September 23.
