The Regional Meteorological Centre (RMC) has forecast heavy rainfall across parts of western Tamil Nadu, including Nilgiris, Coimbatore, and Erode, with the wet spell expected to begin later this week and continue for at least three days.
According to the latest weather bulletin, widespread rainfall activity is likely across the state between April 30 and May 2, driven by a low-pressure system prevailing over Tamil Nadu and adjoining regions.
Meteorologists said the system is expected to sustain rainfall activity for nearly a week, bringing much-needed precipitation to several districts. Districts along the Western Ghats, as well as coastal areas in southern Tamil Nadu, are likely to receive moderate rainfall over the next three days.
The impact is expected to be more pronounced in hilly and adjoining regions due to orographic factors, which could enhance rainfall intensity. Moderate rainfall is also likely over delta districts and coastal belts during this period.
Authorities have advised residents in low-lying and flood-prone areas to remain cautious, as intermittent spells of rain may lead to waterlogging in some areas.
The weather department has issued a specific alert for May 1 and 2, warning of heavy rainfall in districts such as Salem, Krishnagiri, and Dharmapuri. These regions may experience intense showers accompanied by gusty winds, raising the possibility of localised disruptions.
Alongside rainfall, strong surface winds with speeds of up to 40 kmph are expected in several areas during this period.
Officials have also cautioned fishermen and those engaged in outdoor activities to stay updated with weather advisories, as sudden changes in conditions could pose risks.
While the rainfall is likely to provide some relief from prevailing heat conditions, authorities have urged district administrations to remain prepared for contingencies such as fallen trees, power disruptions, and minor flooding.
The meteorological department said it is closely monitoring the system and will issue further updates as the situation develops.
