Nepal Weather: Above-average rainfall forecast, What are the three dangers?

According to meteorologists, the four-month-long rainy season will enter Nepal within next few days.

They say that the monsoon system has reached the Bay of Bengal and will spread across the country through that eastern region.

More than 1,500 millimeters of normal rainfall is projected this monsoon season.

“As long as the average is below 10 percent, we call it a normal monsoon,” said Varun Poudel, a meteorologist at the Meteorological Department of the Department of Water and Meteorology.

“The South Asian Climate Outlook, released by South Asian Meteorologists, has projected above-average rainfall in the region, including Nepal.”

However, experts say that how much water falls in a place and how much water falls in a short period of time or spreads for four months is important.

“Landslides in hilly areas and floods elsewhere should be avoided. Monsoon is characterized by continuous rains and intermittent rains. It rains a lot during this season, especially at night,” he said.

Three dangers of disaster Meteorologists¬†say this year’s monsoon will receive above-average rainfall, but the head of the disaster management agency has warned of three dangers this time around.

Anil Pokharel, chief executive of the National Disaster Risk Reduction and Management Authority, pointed out three dangers:

1. Floods/landslides caused by heavy rains:
Hundreds of lives are lost in floods and landslides in Nepal every year.

“We’ve been able to reduce the number of floods that have killed an average of 100 people each year to 50 recently, but landslides have killed an average of 40-50 people and last year killed an unprecedented 400 people,” Pokhrel said.

He pointed out that the projection of meteorologists with more than normal rainfall could directly increase the challenge of floods and landslides.

2. Diseases that can add to the epilepsy:
Nepal has not yet escaped from the deadly second wave of Covid-19.

Natural disasters during an epidemic are said to double the challenge.

“On the one hand, floods and landslides can affect the transportation of essential supplies such as vaccines if road traffic is disrupted. On the other hand, the rainy season is still considered a disease season.”

“Outbreaks such as diarrhea, snake bites and dengue could further affect public health,” Pokhrel said.

3. Landslide risk on bare mountains:
This year, fires broke out in most parts of Nepal.

For several days, air pollution was exacerbated by thick plumes of smoke in various parts of the country, including Kathmandu.

“We have not seen so many fires. It has had a serious impact. In the rainy season, it could have a greater impact on people’s lives,” he said.

“As a result, there is no longer a situation where trees and plants can absorb water when it rains. That means the soil’s ability to absorb has decreased, which increases the risk of landslides.”

According to Pokhrel, NEA has analysed all these threats and started preparations accordingly.

The changing character of the monsoon

Normally, the monsoon in Nepal would start on June 10 and leave on September 23.

But its character has changed in recent years.

“We have to say that the monsoon in Nepal starts on June 13 and leaves on October 2,” said meteorologist Poudel.

“This is a new date for 2020, based on the 30-year period.”

This time, the pre-monsoon period is not satisfactory, say meteorologists.

Even in winter, when there was little rain and long periods of drought, there was widespread fire and air pollution.
