The hazy weather of the Kathmandu valley witnessed for the past few days was the result of the sudden dip in the mercury, said meteorologists.

Rajendra Shrestha, senior meteorologist at the Weather Forecasting Divison of the Department of Hydrology, told RSS the vapour produced from the earth during the time of excessive cold could not generate rainfall and the sky was seen as hazy and foggy.

This has caused sunny day for few times only after the midday, Shrestha said.

He said it will take at least a week to improve the weather condition of the Kathmandu valley. The weather condition of eastern part of the country is fine while the slight rainfall is occurring in the west. nepalnews.com
