Heat rises across Tarai as westerly wind weakens

Temperatures are climbing across Nepal, with the Tarai plains in Madhesh and Koshi provinces experiencing particularly hot conditions. The Department of Hydrology and Meteorology attributes the heatwave to a weakening of westerly winds. Officials are urging residents to take necessary precautions.

The department noted that while a westerly low-pressure system and local winds persist, the system responsible for recent rainfall has weakened. Senior meteorologist Min Kumar Aryal stated that heavy rainfall is unlikely for the next two to three days, although scattered showers might occur in some areas. The forecast indicates generally cloudy skies in the hills and mountains, with partly cloudy conditions in the Tarai. There's also a chance of moderate rainfall with thunder and lightning in parts of the hills and a few locations in the Tarai of Lumbini and Sudurpaschim provinces, along with possible snowfall in the mountains.

there is no possibility of heavy rainfall for the next two to three days, though scattered showers may occur in some places tomorrow and the day after.

Climate expert Dharam Raj Uprety highlighted the potential consequences of reduced pre-monsoon activity. He explained that less rainfall and increased heat in the Tarai could significantly affect daily life, impacting schools, agricultural workers, and vulnerable populations including women, children, and laborers. The department forecasts maximum temperatures to reach 36–38°C in Simara and 37–39°C in Biratnagar and Janakpur.

a reduction in pre-monsoon activity could lead to less rainfall and more heat in the Tarai, affecting schools, agricultural workers, and vulnerable groups such as women, children, and labourers.
