Synopsis
The Regional Meteorological Centre forecasts very heavy rainfall for northern and interior Tamil Nadu over the next few days due to a deep depression in the Bay of Bengal. Chennai, Vellore, and Ranipet expect intense showers on October 4, with Madurai and Dindigul receiving heavy rain on October 5.
The Regional Meteorological Centre (RMC) has issued an important rainfall forecast for Tamil Nadu. Residents are advised to stay alert as very heavy rain is expected in northern and interior districts over the next few days.
General Heavy Rain Predicted Across Northern Districts Today
According to the RMC, areas such as Chennai, Vellore, and Ranipet are likely to experience very heavy rainfall on October 4, 2025. This could lead to waterlogging on roads and disruption of normal daily activities. Citizens are urged to take precautions, avoid unnecessary travel, and ensure safety during peak rainfall hours.
General Inland Districts to Receive Heavy Rain Tomorrow
Inland regions, including Madurai and Dindigul, are expected to see heavy rain on October 5, 2025. While these areas may not experience the same intensity as the northern districts today, residents should remain cautious, especially in low-lying areas prone to flooding.
General Deep Depression in Bay of Bengal Causes Rain
The heavy rainfall is attributed to a deep depression formed in the Bay of Bengal. This system is generating strong winds and widespread rain across the state. The RMC has indicated that rainfall may continue in certain regions of Tamil Nadu until October 8, 2025, gradually easing after that.
General More Rain Than Normal Expected in Tamil Nadu
The India Meteorological Department (IMD) has predicted normal to above-normal rainfall for most parts of the country during this period. However, some weather models suggest below-normal rainfall in isolated regions, causing confusion among the public. Overall, the north and interior districts of Tamil Nadu are likely to experience heavier-than-usual rainfall over the next few days.
General Widespread Rainfall Across the State
The RMC reports that light to moderate rain is expected at nearly 50% of meteorological stations across Tamil Nadu and Puducherry. Northern districts will see heavy rain today, while interior regions may receive widespread showers through October 5. Citizens should be prepared for possible disruptions in travel and day-to-day life.
General Maximum Temperatures Slightly Above Normal
Alongside rainfall, the RMC has noted that temperatures are expected to be slightly higher than normal in some areas. Maximum temperatures could rise 2–3°C above the seasonal average until October 5, adding to the humid conditions brought by the monsoon showers.
General Northeast Monsoon Brings Relief and Challenges
The Northeast Monsoon is a crucial weather system for Tamil Nadu, bringing both relief and challenges to the state. While farmers may benefit from the rainfall for crops, urban areas could face flooding and traffic disruptions. Residents are advised to follow official updates and safety guidelines during the monsoon period.
General Stay Safe During the Monsoon
Citizens are encouraged to avoid venturing into flooded areas, keep emergency supplies ready, and stay tuned to local weather updates. Precautions are especially important in low-lying and coastal districts prone to waterlogging.
