Weather systems merge to cause rain

Kathmandu, April 15

Kathmandu Valley witnessed thundershowers on Friday and Saturday caused by three weather systems—the westerly winds, the Bay of Bengal’s system, and local effects.

According to the Meteorological Forecasting Division, the westerly winds caused rainfall in the mid to far-western region’s hilly areas for the last two days. Similarly, the eastern parts of the country and Tarai received rainfall from the Bay of Bengal’s weather system.

“The three weather systems merged and caused precipitation across Kathmandu Valley,” meteorologist at the MFD Barun Paudel told The Himalayan Times, adding, “As the three systems are still active, sudden disturbances and clear weather within few hours can be expected for the next few days.” Paudel said the westerly system was entering Nepal through the far-west, while the weather system from the Bay of Bengal was active due to the trough in Bihar of India.

The MFD has predicted generally cloudy weather in the eastern region, and partly cloudy weather in the central and western hilly regions for tomorrow. The weather is predicted to be fair in the rest of the country. Brief rain or thundershowers are likely at a few places of the hilly regions towards noon.

The MFD recorded the highest rainfall in Jiri at 36 mm, followed by Biratnagar at 19 mm, Taplejung 11, Dhankuta 9.7, Simara 8.4, Pokara 6.3, Kathmandu 2.8, and Jomsom 2.7 on Saturday.

According to the MFD, the very short climatic activities caused by local effects are common characteristics of the pre-monsoon season.
