No critical weather disturbances immediately ahead
KATHMANDU, April 20: The pre-monsoon has been more active in Nepal this year compared to last year, according to the Department of Hydrology and Meteorology (DoHM).
March, April and May constitute the pre-monsoon period while June, July and August are the monsoon months. Rain and weather disturbances were higher last winter. “The pre-monsoon is more active compared to last year,” said Barun Paudel, senior meteorologist at the Meteorological Forecasting Division (MFD).
According to Paudel, the weather in Nepal has been impacted by westerly winds, the flow of moisture from the Arabian sea and Indian weather activities . “Local winds are also more active this year. The heating, evaporating and condensation process has triggered thunder, lightening and rain in the different parts of the country,” he said .
He also spoke of the possibility of hailstorms and winds of up to 60-70km/per hour. “However, the chances of tornadoes like the one in Bara and Parsa are low as that was an exceptional case for Nepal.”The weather was not so disturbed last year during this season, according to the MFD. Despite more weather disturbances this year, Kathmandu Valley witnessed only around 31 mm of rain this season whereas it used to record 61 mm on average during this season in previous years. But every week there has been rain in various parts of the country.
“There is need for research on the impact of global phenomena on unusual weather disturbances here,” said Paudel. “However, there are no chances of critical weather disturbances immediately ahead,” he added.
Paudel also informed that the weather would start clearing in the western part of the country from Thursday. “It will be partly cloudy in the central parts Saturday and this pattern will keep reoccurring frequently,” he said. “There will be a clear interval from Sunday in different parts .”
According to DoHM, there was excessive snowfall in the hill districts including Dolpa, Humla, Jumla, Bajura, Darchula, Doti last winter . Kathmandu Valley also witnessed snow this year after an interval of 12 years. Snowfall last took place in the Valley on February 14, 2007.
