IMD predicts heavy rain for several districts in Tamil Nadu
A low-pressure area has formed over the southeast Arabian Sea and the Lakshadweep region, according to the India Meteorological Department (IMD).
This system is the result of a cyclonic circulation extending up to mid-tropospheric levels and is expected to move west-northwest, gradually intensifying into a depression or possibly a cyclonic storm over the next 48 hours.
The cyclonic circulation is causing increased cloud formation and weather activity in the Lakshadweep Islands and parts of Kerala, with potential heavy rainfall expected.
The presence of this low-pressure area has led to heightened monsoon activity, especially in Tamil Nadu and surrounding regions. Tamil Nadu’s nine districts—including Nilgiris, Coimbatore, Tiruppur, Theni, Dindigul, Erode, Salem, Namakkal, and Karur—are forecasted to receive moderate to heavy rains accompanied by lightning and thunder.
The northeast monsoon has already begun in these areas, contributing to significant rainfalls in southern, western, and delta districts.This weather system poses risks such as localized heavy showers and thunderstorms triggered by an atmospheric vortex over the Bay of Bengal joined by the Arabian Sea’s circulation. There is also the potential for rough sea conditions and tidal waves around Lakshadweep.
Authorities have issued warnings for coastal and island regions to be vigilant.The low-pressure area’s impacts are seen in the increased precipitation and stronger winds in the southern peninsular states, which could last for several days. Monsoon withdrawal lines have shifted, and the northeast monsoon is strengthening, promising ongoing rainfall in Tamil Nadu, Puducherry, Karaikal, Rayalaseema, and coastal Andhra Pradesh.
Overall, this cyclonic circulation over the Arabian Sea and Lakshadweep region is influencing the regional weather pattern significantly, bringing much-needed rains but also requiring caution due to potential flooding and storm conditions, especially in coastal and low-lying areas.
