Bhubaneswar, Sep 27: The India Meteorological Department (IMD) has forecast another spell of intense rainfall across Odisha starting October 1, triggered by a fresh low-pressure system forming over the Bay of Bengal.

According to IMD, a cyclonic circulation is likely to develop over the North Andaman Sea around September 30, which may evolve into a low-pressure area over the adjoining central Bay of Bengal by October 1. This system is expected to bring widespread rainfall across the state, with thunderstorms and lightning in several districts.

Currently, an existing trough over the central Bay of Bengal is active over interior and southern Odisha. It is expected to weaken and become a well-marked low-pressure area within the next 24 hours, continuing to influence rainfall across the region.

The Meteorological Department has issued a yellow warning for heavy rainfall accompanied by lightning in 10 districts including Jagatsinghpur, Kendrapada, Jajpur, Mayurbhanj, Keonjhar, Bargarh, Balangir, Nuapada, Nabarangpur, and Malkangiri.

Coastal districts such as Ganjam, Gajapati, Nayagarh, Khordha, Puri, Cuttack, Bhadrak, Baleswar, and others are also under yellow alert for moderate to heavy rainfall.

Wind speeds are expected to range between 30 to 40 km/h during the rain spells. The IMD has advised caution for residents in vulnerable areas and urged farmers and fishermen to stay updated with weather advisories.

In the past 24 hours, most parts of Odisha received rainfall, with 24 stations recording heavy showers. The highest rainfall was recorded at Salebhata in Balangir district, which received 123.2 mm.

The IMD has also warned of continued rainfall over coastal and northern interior Odisha for the next two days, though no fresh warnings have been issued for some regions. However, the formation of the new low-pressure system is expected to intensify rainfall again from October 1.
