Kathmandu, August 18 The Meteorological Forecasting Division has said that some parts of the country in the western region are likely to receive moderate to heavy rainfall for the next few days due to low pressure area which is currently over eastern Nepal. “The low pressure area developed in the Bay of Bengal has arrived near eastern Nepal by today and is gradually advancing to the western region. At the same time, monsoon low pressure line is also over the same region due to which some parts of the central and eastern regions are likely to receive light to moderate rainfall,” said a monsoon update issued by the MFD. However, some parts of the western region are likely to experience heavy rainfall. “Heavy rains are likely to have an impact on watershed areas and rivers that flow through the western regions,” it warned. The prevailing low pressure area developed in Bay of Bengal is likely to infuse moisture into the air in some parts of the country. The onset of monsoon was officially declared on June 15, five days later than the normal date this year. Monsoon in Nepal generally starts on June 10 and spreads across the country in a few days, and remains effective till September 23. It was delayed by three days this year. Earlier, MFD had forecast that the country was is most likely to receive normal rainfall during this year’s monsoon.
