Sporadic and light rainfall that began yesterday has marked the beginning of this year's pre-monsoon that usually lasts for three months in the country.

The temperature had slightly dropped in the last two days after some rainfall in the mountainous region. The Department of Hydrology and Meteorology said in a bulletin that there might be light to medium rainfall in Bagmati and Gandaki provinces, especially in the hilly areas till tomorrow.

Rainfall has caused the temperature to drop for the last couple of days, but meteorologists say such temporary decline in temperature due to rainfall will increase the latent heat at the ground level a couple of days later. The pre-monsoon season remains active in Nepal from March to May.

Meteorologist Manju Basu said that the pre-monsoon period, which is also spring time, is marked by frequent changes in weather in the evening, especially in the hilly regions. "We might now frequently notice that evenings get cloudy and look as if it will rain right now. People can also feel rapid wind and thunderstorm in the evening," Basu said.
