Monsoon to go when September ends

Weathermen have predicted that the monsoon — that has wreaked havoc across the country by triggering floods and landslides — is here to stay until September.

According to Meteorologist Raju Cradhananda of Department of Hydrology and Meteorology monsoon has travelled from the foothills of Himalayas to India, resulting in the decrease of rainfall in Nepal. However, the moisture will remain in the atmosphere and the country will witness minor drizzles throughout September, he said.

Cradhananda said heavy rainfall occurs usually in July and August. “Transportation of monsoon to India from Nepal during September is a normal phenomenon,” he said.

According to him, late arrival of monsoon this year took its toll in the country’s agriculture. “Due to delayed arrival of monsoon, farmers were unable to plant paddy on time,” he said, adding that monsoon, this year, was delayed by at least 10 days.

While June 10 is said to be the right date for the monsoon to arrive, the rainfall was witnessed this year only on June 20.

A weak beginning of monsoon, however, turned fierce by mid-July until mid-August. Spells of incessant rainfall resulted in floods and landslides in Western Nepal and other parts of the country.

“However, the fierce rainfall was often shortlived,” said Cradhananda. “In stead of mild downpours which last for several days, heavy rainfall at a particular place this year was only two-three days long.”

According to him, maximum rainfall recorded this year was somewhere above 400 mm in a single day. “It was the nature of rainfall rather than its length that caused the disasters,” he said.

The Department is yet to assess the data of highest and lowest recorded rainfall this monsoon. “The assessment will be done once the monsoon is over around the end of September,” Cradhananda said.
