The India Meteorological Department (IMD) has forecast heavy rainfall accompanied by thunderstorms and lightning across three southern Tamil Nadu districts — Theni, Dindigul, and Madurai — on Thursday, 5 November 2026, as an atmospheric disturbance continues to influence weather conditions across the region.
Thursday Forecast: Districts on Alert
Heavy showers are likely at isolated locations in Theni, Dindigul, and Madurai during the day, the weather department said. Moderate rainfall could occur at one or two places in districts adjoining the Western Ghats, northern Tamil Nadu, and the southern parts of the state. Thunderstorms and lightning are also likely in areas experiencing intense rainfall activity.
In Chennai, the weather is expected to remain partly cloudy, with light to moderate showers forecast in certain parts of the city. Rainfall activity is likely to vary across localities, with some neighbourhoods seeing brief spells while others remain largely dry.
Friday Outlook: Seven Districts in the Crosshairs
The IMD has predicted an expansion of heavy rainfall across southern Tamil Nadu on Friday, 6 November 2026. Seven districts — Theni, Dindigul, Madurai, Thoothukudi, Ramanathapuram, Pudukkottai, and Sivaganga — have been identified as likely to receive heavy rainfall at isolated places. The rest of Tamil Nadu is expected to experience light to moderate rainfall during the same period, indicating that wet weather conditions could persist across several districts over the next two days.
Northeast Monsoon Context
The forecast comes during Tamil Nadu's northeast monsoon season, which accounts for a substantial share of the state's annual rainfall — particularly in coastal and southern districts. Rainfall during this period plays a critical role in replenishing reservoirs, irrigation tanks, and groundwater resources.
Notably, intense spells of rain can also create difficulties for motorists and residents in low-lying areas, particularly where drainage infrastructure is inadequate. Southern districts are expected to remain the principal areas of concern through at least Friday.
Advisory for Residents
Residents across the affected districts have been advised to monitor official IMD bulletins for real-time updates on rainfall intensity, thunderstorm alerts, and any revision in district-level forecasts. The department indicated that the prevailing atmospheric disturbance over southern Tamil Nadu and adjoining areas is expected to sustain widespread cloud formation and rainfall activity in several parts of the state over the coming days.
Point of View
But persistent atmospheric disturbances during the northeast monsoon carry real economic weight for Tamil Nadu — this is the season that determines reservoir levels and rabi crop prospects across the south. The expansion from three districts on Thursday to seven on Friday signals that the disturbance is intensifying rather than dissipating. What the forecast does not yet address is flood-preparedness in low-lying urban pockets of Madurai and Thoothukudi, where drainage systems have historically struggled during concentrated downpours. Local administrations in those districts should treat this as an action window, not a passive watch.
