Monsoon, which normally enters on June 30, entered from eastern Nepal on Thursday night 15 days earlier this year. Monsoon, which is caused by the weather effect carried by the water vapor air flow from the Bay of Bengal, usually enters Nepal within 10 to 13 days after entering the southern Indian state of Kerala, i.e. on June 13 (June 30), but this year it entered before the Sardar date.
According to the records of monsoon arrival and departure of the Department of Water and Meteorology, this time the monsoon has set in at the earliest in 29 years (after May 31, 1996). Monsoon entered Kerala last Saturday, eight days before Sardar.
Monsoon, which entered Nepal on Thursday, has spread to most parts of Koshi province, according to the weather forecast division of the department. The division issued a 'monsoon arrival bulletin' at 3 pm on Friday and mentioned that light to moderate monsoon rains are occurring in most of the meteorological centers of Koshi province. The department has informed that the effect of monsoon will spread throughout the country in a few days.
Generally, for a monsoon, the wind should blow from east to west. Apart from Koshi province, the influence of western wind and local wind is still the same in the rest of the country and the weather conditions are being continuously monitored by the division. Monsoon process lasts for an average of 112 days . 80 percent of annual rainfall occurs during the monsoon period. According to the
division, there is a possibility of light to moderate rain with thunder and lightning at some places till Sunday in the hilly areas of Koshi region. There is a possibility of light snowfall in few places in the Himalayan region. Mild to moderate years are likely in other areas as well.
Dr. Madan Sigdel, associate professor of the Central Department of Water and Meteorology of Tribhuvan University, said that although the monsoon has arrived, there is a possibility that the monsoon will 'break' for a week after next Monday. According to him, there must be water vapor in the air for monsoon to occur, without that, the weather system in which dry air flows is called monsoon 'break'.
There are two reasons for the break of the monsoon, one is the lack of development of the low pressure system formed in the Bay of Bengal, which creates and continues the monsoon, and the other is when the effect of the westerly wind is removed in Koshi, but it is still active in other parts of the country, he said. According to Sigdel, if the expanding monsoon breaks, it cannot be sure whether it will reach other parts. Also, on Saturday, there is a possibility of heavy rain in one or two places of Koshi province and light rain and snow in the highlands and mountain areas, as it may affect daily life, agriculture, health, road and air transport.
The Department of Hydrology and Meteorology has predicted above-average rainfall this year. According to the department's analysis, last year was the heaviest rain in the history of 77 years, and disasters such as floods, landslides, heavy rains and lightning caused human and material damage. According to the National Disaster Risk Reduction and Management Authority's "preliminary assessment of damage and loss", there was a loss of more than 46 billion 684 million 43 million in physical infrastructure including roads, bridges, hydropower, agriculture and livestock, education, health and irrigation.
The National Disaster Authority has estimated that around two million people will be affected by monsoon disasters this year. The authority has also issued a national action plan for monsoon response to reduce damage caused by monsoon disasters.
In order to minimize the damage caused by the monsoon that comes ahead of Sardar, experts have also suggested to take precautions and precautions. "If there is more rain, there is a risk of disaster. In the cities like Kathmandu Valley where the roads are under construction and there is rapid urbanization, riverbeds will increase, the coastal settlements are at risk," says Sigdel, associate professor of the Central Department of Water and Meteorology of Tribhuvan University. He said that even though the sewers of Kathmandu Valley have not been cleared due to weather conditions, they should be cleaned immediately and the flood roads should be opened. Meteorologist David Dhakal of the Weather Forecasting Division said that there is a possibility of heavy rains during the monsoon period in Nepal as well.
