Southwest Monsoon Advances in TN: Heavy Rain Alert for Western Ghats Districts

The southwest monsoon is set to advance over Tamil Nadu, with the Regional Meteorological Centre issuing heavy rain warnings for Western Ghats districts including Nilgiris, Theni, and Dindigul. Widespread rainfall with thunderstorms, lightning, and gusty winds up to 50 kmph is expected over the next few days.

Southwest monsoon set to advance in TN; heavy rain alert issued for Western Ghats districts

Chennai, June 7

Conditions have become increasingly favourable for the further advancement of the southwest monsoon over Tamil Nadu, with the Regional Meteorological Centre forecasting widespread rainfall activity across several districts, particularly along the Western Ghats, over the coming days.

The weather office has issued a warning for heavy to very heavy rainfall accompanied by thunderstorms, lightning and gusty winds reaching speeds of 40 to 50 kmph in parts of the state for the next few days.

The most intense rainfall is expected over the Nilgiris, Theni and Dindigul districts, as well as the ghat areas of Coimbatore district, where isolated locations could experience very heavy downpours. Meteorologists said the strengthening monsoon conditions are likely to bring significant rainfall to the Western Ghats region, offering relief from recent heat and dry weather while also raising the possibility of localised flooding, landslides and disruptions in vulnerable hill areas.

Apart from the districts under the heavy to very heavy rain warning, the RMC has forecast heavy rainfall accompanied by thunderstorms at isolated places in Erode, Salem, Dharmapuri, Krishnagiri, Tirupattur, Vellore, Ranipet, Tiruppur, Madurai, Virudhunagar and Kanyakumari districts.

Similar conditions are expected in the ghat regions of Tenkasi and Tirunelveli districts.

Officials have advised residents in hilly and low-lying areas to remain vigilant, particularly in districts likely to receive intense rainfall.

Strong winds and lightning associated with thunderstorms could also affect normal activities in several parts of the state.

While rain-bearing clouds are expected to dominate much of western and southern Tamil Nadu, the weather office noted that uncomfortable weather conditions are likely to persist over the northern coastal belt.

High daytime temperatures combined with elevated humidity levels are expected to result in sultry conditions across several coastal districts. Chennai continued to experience intense heat, recording the highest maximum temperature in the state at 40.4 degrees Celsius on Saturday. The combination of heat and humidity is expected to keep conditions uncomfortable despite the approaching monsoon.

Meanwhile, rainfall activity has already intensified in parts of southern Tamil Nadu. Nalumukku in Tirunelveli district recorded the highest rainfall in the state during the past 24 hours with 17 cm, while Mylar in Kanyakumari district received 9 cm, indicating the strengthening influence of the southwest monsoon over the region.

Living in Coimbatore, I can already see the dark clouds gathering near the ghat areas. The forecast says gusty winds up to 50 kmph - that's no joke! Hope people in mudslide-prone areas shift to safer places voluntarily. And yes, Chennai folks, you'll have to bear the humidity a bit longer. Monsoon takes its own sweet time reaching the coast! 😅

Interesting to see how the monsoon dynamics work in Tamil Nadu. Coming from Canada, I'm amazed that 17 cm of rain in 24 hours is considered "normal" here. Back home, that would cause state of emergency. Hope the local authorities have proper early warning systems in place for the hill districts. Stay safe, everyone.

As someone from Dindigul, I can tell you - when they say "heavy rainfall" in the Western Ghats districts, they mean business! Last year our village road got washed away completely. The district administration should proactively deploy NDRF teams in vulnerable areas rather than waiting for disaster to strike. Also, please fix the drainage in Chennai - 40 degrees with humidity is a health hazard! 😤

The contrast is fascinating - while the Western Ghats brace for flooding, Chennai is still sweltering at 40.4°C. That's typical Tamil Nadu weather for you! One part of the state gets drenched, another part is praying for rain. I just hope the agriculture sector benefits properly from this. Our farmers in the Cauvery delta need every drop they can get.
