Although the monsoon low-pressure line is around its usual position, moist air coming from the Arabian Sea and the Bay of Bengal is causing rainfall in Nepal.
Last night, a few places in Koshi Province saw heavy to very heavy rainfall. In the past hour too, places like Naubasta in Banke and Gaighat in Udayapur recorded heavy rain.
Senior meteorologist Shanti Kandel said that the moist air from the Arabian Sea and the Bay of Bengal is the main reason for the rainfall. According to her, this effect is expected to continue for the next two to three days.
“Clouds are increasing. Since last night, rainfall activity has gone up,” Kandel said. “Koshi Province has received heavy to very heavy rainfall, followed by Madhesh and Lumbini provinces.”
According to the Department of Hydrology and Meteorology, Kechana in Jhapa district of Koshi Province recorded 124.8 mm of rain in the past 24 hours. Damak recorded 92.8 mm, and Dingla 94.6 mm.
In Udayapur’s Gaighat, 54.6 mm of rain fell in just one hour. Rainfall above 50 mm in one hour is considered heavy rain.
Madhesh Province also saw rainfall in places like Golbazar and Rupani in Siraha district.
Rainfall was also recorded in Naubasta of Banke, Siddhara of Arghakhanchi, and Rangsing, among other places.
According to meteorologist Kandel, in the coming days, the monsoon low-pressure line may shift northward toward Nepal. If this happens, the intensity of rainfall could increase further.
“Right now, Jhapa and Banke have been seeing heavy rain for the past three hours, and there is a possibility of more intense rainfall in the eastern Terai,” Kandel said.
She added that instead of continuous rainfall across the country, heavy showers are likely only in certain areas.
