Heavy rains forecast for Puducherry and Tamil Nadu.

Heavy rains forecast for Puducherry and Tamil Nadu.
  • Heavy rain expected in Puducherry and Tamil Nadu.
  • Low-pressure area to impact coastal regions.
  • Thunderstorms predicted for Tuesday and Wednesday.

The Regional Meteorological Centre (RMC) in Chennai has issued a weather advisory predicting heavy rainfall in several districts of Tamil Nadu and the union territory of Puducherry. This significant weather event is anticipated to commence on December 24th, 2024, and continue into December 25th, 2024. The RMC attributes this impending deluge to a weakened depression over the Bay of Bengal, which is expected to evolve into a well-marked low-pressure area. This low-pressure system is projected to move towards the southwest Bay of Bengal, positioning itself near the north Tamil Nadu and south Andhra Pradesh coasts by Tuesday. The severity of the rainfall is expected to be most pronounced in specific districts, with Chengalpattu, Villupuram, and Cuddalore in Tamil Nadu, and Puducherry itself facing the brunt of the heavy downpour. The RMC's forecast highlights that these areas should brace themselves for substantial rainfall throughout Tuesday and Wednesday.

The meteorological agency's prediction also includes a broader, albeit less intense, impact on other regions. Light to moderate rainfall is anticipated in several areas of north coastal Tamil Nadu. This less severe rainfall will likely affect a wider geographic area compared to the heavy rainfall concentrated in the aforementioned districts. In addition to the anticipated rain, the forecast includes the probability of thunderstorms in isolated pockets across the rest of Tamil Nadu, Puducherry, and Karaikal. This suggests that while widespread heavy rain is not expected everywhere, the potential for localized thunderstorms remains a concern for several regions across the two entities.

The forecast also extends to cover the immediate preceding days. The RMC anticipates light to moderate rainfall in isolated locations across Tamil Nadu, Puducherry, and Karaikal on Monday, December 23rd, 2024. This indicates that the onset of the weather system will begin gradually, with lighter precipitation prior to the heavier downpours expected on Tuesday and Wednesday. Furthermore, mist or haze is expected during the early morning hours in isolated locations. Chennai, the state capital, is specifically predicted to experience partly cloudy skies with light to moderate rain in some areas on Monday. This suggests a gradual intensification of the weather system as it progresses towards its peak on Tuesday and Wednesday. The contrast between the dry weather reported on Sunday and the predicted rainfall emphasizes the rapid change in weather conditions.

The prediction of heavy rainfall necessitates a preparedness response from the relevant authorities and the affected populations. Authorities in the affected districts should activate their emergency response plans, including ensuring the readiness of flood control measures, evacuation plans for vulnerable populations, and the establishment of temporary shelters. Regular updates from the RMC should be disseminated to the public to keep them informed about the changing weather conditions. Residents in the affected areas are advised to monitor weather reports and take necessary precautions to safeguard themselves and their property. This includes securing loose objects that could be damaged by strong winds, staying indoors during periods of heavy rain, and being aware of the risks associated with flooding.

The accuracy of weather forecasts, while constantly improving, is not perfect. This prediction should be viewed as a probabilistic assessment rather than a definitive statement of what will happen. While the RMC uses sophisticated models and data to generate these forecasts, unforeseen weather patterns can still occur. Therefore, continuous monitoring of updates from the RMC and other relevant sources is crucial for individuals and organizations to adapt to any changes or unexpected developments in the weather conditions. The dynamic nature of weather systems demands vigilance and a readiness to respond to changing circumstances. Ongoing monitoring is essential for effective mitigation and safety measures.
