The Regional Meteorological Centre (RMC) has alerted several Tamil Nadu districts of heavy rain due to a cyclonic circulation near Chennai. The weather system, affecting both the Bay of Bengal and northern Tamil Nadu, is causing widespread rainfall, particularly over Coimbatore and the Nilgiris. Chennai is expected to experience only light rain for now, but the situation might escalate if the system intensifies further. Residents have been advised to keep an eye on weather updates, as other parts of the state remain under intense summer heat.

Chennai, May 15: The Regional Meteorological Centre (RMC) has issued a heavy rain alert for several districts across Tamil Nadu till May 18 due to an upper air cyclonic circulation prevailing in the region, an official said on Thursday.

Key Points

1

RMC warns Tamil Nadu of heavy rainfall due to cyclonic circulation

2

Chennai to see light rain with potential escalation to more rainfall

3

Coastal Ghat regions likely experience relief from extreme heat conditions

4

Residents advised to stay informed on weather updates and take precautions

According to the RMC, the cyclonic circulation currently lies in the southwest Bay of Bengal and extends to the north coastal regions of Tamil Nadu at an altitude of 1.5 km above sea level.

It is also connected to a system over the southeast Bay of Bengal, triggering widespread rainfall activity in the state.

Fifteen districts, including Erode, Krishnagiri, Dharmapuri, Vellore, Salem, and Thanjavur are likely to witness heavy downpours over the next few days.

Chennai and its neighbouring areas are expected to experience light rain with partly cloudy skies.

The RMC has further forecast that from May 15 to May 21, light to moderate rainfall accompanied by thunderstorms, lightning, and gusty winds is expected in isolated places across Tamil Nadu, Puducherry, and Karaikal regions.

Weather blogger Srikanth noted that based on the current wind convergence and circulation patterns, Chennai could receive rainfall for the next two to three days.

However, he added that if the upper-air cyclonic circulation over north coastal Tamil Nadu and the southeast Bay of Bengal intensifies further, it could lead to the formation of a low-pressure area -- potentially bringing more widespread rainfall to the region.

He also noted that the usual sea breeze that cools the city could weaken due to the early onset of the southwest monsoon over the Andaman Sea and parts of the Bay of Bengal.

The RMC has advised residents to stay updated on weather alerts and take necessary precautions, particularly in districts forecasted to receive heavy rainfall.

The Regional Meteorological Centre (RMC), Chennai, has issued a heavy rainfall forecast for parts of Tamil Nadu, particularly the Ghat regions of Coimbatore, the Nilgiris, and several interior districts, till Friday (May 16).

While these areas are expected to experience relief from the heat, other parts of the state will continue to reel under intense summer conditions.

On Tuesday, seven weather stations in Madurai, Vellore, Erode, Karur, Palayamkottai, and Tiruchy recorded maximum temperatures above 40 degrees Celsius.

The Madurai airport station once again reported the highest temperature in the state, touching 41 degrees Celsius for the second consecutive day.

Finally some relief from this scorching heat! 🌧️ But I hope the administration is prepared - last year's floods in Chennai were terrible. They better clean the stormwater drains this time.

As a farmer in Thanjavur district, we desperately need this rain for our crops. But heavy downpour all at once can damage the fields. Hope it's well distributed over days.

Why is the weather department giving alerts just 2-3 days in advance? They should improve forecasting technology. My brother's wedding is in Salem this weekend and now we're worried about travel plans.

Good that Chennai is only expecting light rain. Our city infrastructure can't handle heavy rainfall - roads turn into rivers within hours! Corporation should use this warning period to prepare emergency teams.

The temperature difference between Madurai (41°C!) and Nilgiris will be extreme. Climate change is making our weather patterns so unpredictable. Stay safe everyone, especially outdoor workers.

Hope the electricity department is ready this time. Last monsoon, we had power cuts for days in Coimbatore. Also, people should stop throwing garbage in drains - that's half the flooding problem right there.
