KATHMANDU, Mar 6: This year's pre-monsoon weather has started. The Meteorological Forecasting Division has stated that the weather in the hilly region of the country would remain continually affected as the pre-monsoon holds sway for three months – March, April and May. 

The pre-monsoon is characterized by sunny days and intermittent thunder shower towards the afternoon or the evening, senior meteorologist Meen Kumar Aryal said. 

According to him, the pre-monsoon has begun as the local wind has started to have its influence. Its impact has been seen also because the temperature has started to go up. 

Aryal added that the weather in the hilly region gets affected frequently during these three months. Rainfall takes place for a short period of time. Even within the Kathmandu Valley, rain might take place in one area while no rain in another area. 

Although the effect of the pre-monsoon is seen in the hilly region, it will not be seen in other regions. During the pre-monsoon, there is a likelihood of lightning during this time due to the combined influence of the Westerly wind and the local wind. 

There was no immediate likelihood of rainfall in other regions, except in the hilly region, as new weather system has not yet developed, the Division said.
