Chennai: The India Meteorological Department (IMD) has forecast moderate rainfall in South Tamil Nadu and the Western Ghats districts until March 1, following the formation of a low-pressure area over the Bay of Bengal.

The Regional Meteorological Centre (RMC), Chennai, said a low-pressure system over the southwest Bay of Bengal and adjoining central Bay formed on the morning of February 23. The system is expected to weaken gradually while moving north-eastwards.

Low-pressure system, cyclonic circulation to influence the weather

In addition, a cyclonic circulation over the southeast Arabian Sea off the south Kerala coast is likely to impact weather conditions over adjoining regions.

Under the combined influence of these systems, moderate rain is likely at isolated places across southern Tamil Nadu, the Western Ghats region and neighbouring districts from February 24 to March 1, the IMD said in a press release.

Warning for fishermen: Squally weather, winds up to 60 kmph

The IMD has issued a fishermen advisory, warning of squally weather conditions over the northern parts of the southeast Bay of Bengal and adjoining southwest, central and east-central Bay regions.

Wind speeds may reach up to 60 kmph, leading to rough sea conditions. Fishermen have been advised not to venture into the specified sea areas during this period.

IMD to monitor the system closely

The weather department said it will continue to track the low-pressure system and cyclonic circulation and issue updates as required.

With intermittent rain likely over the coming days, residents in southern Tamil Nadu districts have been advised to remain vigilant and follow official weather advisories.
