Chennai is currently witnessing a surge in rainfall, surpassing the usual November norms. The precipitation is anticipated to persist for the next 3-4 days, extending its presence into the initial days of December.
Unusual November Rainfall in Chennai
Renowned for its substantial November rainfall, Chennai is once again grappling with above-average precipitation this month. The Nungambakkam Observatory has documented a rainfall exceeding 400 mm, surpassing the monthly average of 376.6 mm. The forecast indicates a continuation of rain for the next 3-4 days, stretching into early December. This extended rainfall period is attributed to a developing weather system in the Bay of Bengal.
Recent Weather Patterns in Chennai
Recent weather patterns in Chennai have seen overnight showers and morning rain on Monday, following a day of heavy rainfall on Sunday. The India Meteorological Department (IMD) predicts a partly cloudy sky with light to moderate rain, accompanied by thunderstorms and lightning in specific areas of Chennai on November 27.
Impact Beyond Chennai: Heavy Downpours in Tamil Nadu
The impact of persistent rainfall extends beyond Chennai, affecting multiple districts in Tamil Nadu. According to S Balachandran, Deputy Director General of the Regional Meteorological Centre (RMC), a low-pressure area is anticipated to form in the South Andaman Sea and its vicinity around November 26. This system is expected to move west-northwestward, intensifying into a depression over the southeast Bay of Bengal by November 27. Consequently, moderate rainfall is expected in various parts of the state.
Regional Meteorological Centre’s Forecast
The Regional Meteorological Centre (RMC) in Chennai has forecasted light to moderate rainfall, coupled with thunderstorm lightning, over several districts of Tamil Nadu, Puducherry, and Karaikal on Monday. Chennai and its surrounding areas have already witnessed moderate rainfall since early morning. A total of 10 districts in Tamil Nadu are likely to experience rainfall in the coming hours.
Weather Developments: Low-Pressure System Anticipated
As weather conditions evolve, the Regional Meteorological Centre (RMC) highlights the potential development of a low-pressure area in the South Andaman Sea and its nearby regions by November 26. This meteorological phenomenon is projected to move in a west-northwest direction, gaining intensity and evolving into a depression over the southeast Bay of Bengal by November 27. As a consequence, several regions in Tamil Nadu can brace themselves for a continuation of moderate rainfall.
Chennai and Surrounding Areas: Ongoing Rainfall Trends
Chennai and its surrounding areas have already borne witness to overnight showers and morning rain, marking a sequence of heavy rainfall over the weekend. The India Meteorological Department (IMD) suggests that November 27 will see a partly cloudy sky, with the likelihood of light to moderate rain, accompanied by thunderstorms and lightning in specific areas of Chennai.
Beyond Chennai: Widespread Impact on Tamil Nadu
In addition to Chennai, numerous districts in Tamil Nadu have encountered substantial downpours in recent days. Deputy Director General S Balachandran of the Regional Meteorological Centre (RMC) anticipates the formation of a low-pressure area, contributing to the continuation of moderate rainfall in various parts of the state. This underscores the need for residents in affected areas to stay informed and take necessary precautions.
IMD’s Projections: Varied Weather Patterns
The India Meteorological Department (IMD) projects a varied weather scenario in the upcoming days, with a mix of cloud cover, light to moderate rain, and the possibility of thunderstorms and lightning. Residents are advised to stay updated on the latest weather forecasts and advisories issued by the authorities to ensure safety during these weather fluctuations.
Preparedness and Safety Measures
As the weather continues to be unpredictable, it is crucial for residents and authorities alike to remain vigilant. Adequate preparedness and safety measures should be in place, especially in areas prone to flooding or other weather-related incidents. The collaboration between meteorological agencies and local authorities becomes pivotal in ensuring the dissemination of timely and accurate information to the public.
Conclusion
In summary, Chennai and several districts in Tamil Nadu are currently experiencing above-average rainfall, with projections indicating its persistence for the next few days. The development of a low-pressure system adds a layer of complexity to the weather patterns, requiring a proactive approach in terms of preparedness and safety measures. Residents are urged to stay informed, follow official advisories, and take necessary precautions to navigate through this period of heightened meteorological activity.
