Monsoon trough normalises


The monsoon trough has again returned to its normal position and reduced rainfall is expected in a day or two, Meteorological Forecasting Division said.

According to a weather outlook published by MFD on sunday, despite weakened rainfall, moderate isolated thundershowers may occur at a few places in the country.

“Localised temporary thundershowers at a few places in the country might occur and moderate type of rain is possible at a few places of the far-western hilly region tin the late afternoon,” it said.

Earlier, many parts of the country, including Kathmandu Valley, had experienced four virtual dry days before receiving abundant rainfall on July 15.

Weather officials said it is likely to take a day or two for the rain-producing system to spread. Until then, there is probability of moderate rainfall only in some places of the country.

Out of 19 meteorological stations, only Nepalgunj, Kathmandu, Taplejung, Biratnagar, Pokhara, Okhaldhunga, Dadeldhura and Jumla received 17 mm, 13 mm, 10 mm, 9 mm, 9 mm, 6 mm, 3 mm 1 mm rainfall respectively in the last 24 hours, ending at 8.45am on sunday.

The average monthly rainfall for July was 363.4 mm in Kathmandu. It has so far received 282 mm.

The Valley is likely to receive monthly average rainfall, MFD officials said.

The onset of this year’s monsoon was officially declared on June 13 — three days later than the normal date of monsoon onset —  after the rain-bearing system built up and entered the eastern parts of the country.

Monsoon generally starts on June 10 in Nepal and spreads over the country in a few days, and remains effective till September 23 in Nepal.

Nepal receives an average of 80 per cent annual rainfall during monsoon.
