Low-pressure system to bring heavy rain to eastern India

The India Meteorological Department (IMD) has issued alerts for heavy rainfall across eastern India as a low-pressure system moves toward Jharkhand and the western districts of West Bengal. The system is expected to intensify precipitation in the region over the coming days, with meteorologists tracking its progression closely.

Sub-Himalayan districts including Darjeeling, Kalimpong, Alipurduar, and Jalpaiguri are anticipated to experience significant rainfall until the morning of August 21. These foothill areas, which receive substantial monsoon precipitation during this season, are likely to witness heavier-than-normal downpours as the system moves through the region.

The IMD's forecast underscores the need for residents and authorities to remain vigilant, particularly in vulnerable areas prone to flooding and landslides. Officials have advised the public to monitor weather updates regularly and take necessary precautions as the low-pressure system develops.

The monsoon season continues to influence weather patterns across South Asia, with such systems playing a crucial role in the subcontinent's rainfall distribution during the June-September period.
