The Regional Meteorological Centre (RMC), Chennai, has issued a forecast predicting heavy rains in several districts of Tamil Nadu starting from November 11, with widespread monsoon showers expected to persist through November 18. According to weather experts, this signals the return of the northeast monsoon, which had temporarily eased, but is now set to bring active rainfall across the region.

The meteorological department has specifically warned of heavy rains in isolated areas of Thanjavur, Tiruvarur, Nagapattinam, Mayiladuthurai, Pudukkottai, Kanniyakumari, and Karaikal, with the possibility of light to moderate showers in parts of Tamil Nadu, including the state capital, Chennai. These districts, particularly in the southern and coastal regions, are expected to experience significant rainfall as the monsoon progresses.

According to a weather blogger,  the delay in the onset of active monsoon rainfall can be attributed to a low-pressure area forming off the coast of Sri Lanka. This low-pressure system has been impacting the regional weather pattern, causing a temporary reduction in rainfall across most of Tamil Nadu.

From November 11 to November 18, the state can expect widespread, active monsoon showers, with some areas likely to experience heavy rains. The northeastern districts along the coast, including Chennai, are likely to receive moderate rainfall, while areas further inland, such as the delta districts and parts of southern Tamil Nadu, may experience heavy showers due to the influence of the low-pressure system.

The active monsoon conditions are expected to continue, with the potential for localized flooding and disruption in some areas. The RMC has advised residents, especially in flood-prone districts, to remain alert and prepared for the possible impact of heavy rains.

As the monsoon intensifies, agricultural activities, particularly in the delta regions, may be impacted due to the excessive rainfall. Farmers, particularly in districts like Thanjavur, Tiruvarur, and Nagapattinam, which are known for their agricultural output, will need to closely monitor the weather to safeguard crops from waterlogging and potential damage caused by strong winds and heavy rainfall.

In urban areas, including Chennai, the rains are expected to bring cooler temperatures, providing some relief from the heat. However, the monsoon showers are likely to cause traffic disruptions and waterlogging in low-lying areas, potentially leading to delays in daily commuting. City residents are advised to plan their travel accordingly.

The monsoon season in Tamil Nadu, which typically spans from October to December, is now set to resume with heavy rainfall expected in several parts of the state from November 11.
