Tamil Nadu is likely to receive heavy rain over the next six days as the northeast monsoon intensifies, with Ramanathapuram and Thoothukudi among the southern districts facing the possibility of heavy to very heavy rainfall, according to weather officials quoted by Dinamalar. The warning comes after widespread rain across the state during the past 24 hours.
Officials said very heavy rain was recorded in several locations, while three districts received heavy rain and 13 districts recorded moderate rainfall. Chennai’s MGR Nagar recorded the highest rainfall in the state during the period, with 13 centimetres. The figures underline the uneven distribution of rainfall across the state, with southern and delta districts receiving more than their normal levels, according to the report.
The northeast monsoon is expected to remain active until October 26 before gradually weakening. Weather officials said the Western Ghats, delta districts and southern districts have been receiving rainfall above normal. The forecast is significant for urban administrations in these areas because prolonged or intense rainfall can place pressure on road networks, storm-water systems and other civic infrastructure, although the report does not provide district-wise warnings for specific facilities or transport services.
A low-pressure area has formed over the southwest Bay of Bengal and adjoining coastal areas of southern Tamil Nadu. Officials said it is not expected to develop into a cyclone. Another low-pressure area may form on October 23 over the southeastern Bay of Bengal and adjoining central-eastern areas, with a westward movement possible, the report said.
For Chennai, the immediate forecast is for moderate rain for another three days, with no likelihood of heavy rain during that period. The city has nevertheless recorded significant rainfall in MGR Nagar, making localised differences within the metropolitan area relevant to how residents experience the weather. The available report does not specify whether any schools, offices, transport services or civic operations have been suspended or altered.
The forecast places the focus on the capacity of local administrations to monitor rainfall across districts with different levels of exposure. Southern coastal districts, delta areas and locations near the Western Ghats are expected to remain the principal areas of concern under the current outlook. Officials have indicated that the low-pressure system is unlikely to become a cyclone, while the broader northeast monsoon spell is expected to ease gradually after October 26.
