Heavy rain is likely at isolated places in four southern Tamil Nadu districts on Wednesday, October 14. The districts named in the IMD warning are Ramanathapuram, Thoothukudi, Tirunelveli and Kanyakumari.

The warning means heavy rainfall is possible at isolated locations within these districts, rather than necessarily across each district as a whole. Thunderstorms and lightning are also likely at one or two places across Tamil Nadu, Puducherry and Karaikal on October 14.

Moderate rain is forecast in several other districts, including Chennai, Tiruvallur, Chengalpattu, Villupuram, Cuddalore, Thanjavur, Tiruvarur, Mayiladuthurai, Nagapattinam and Pudukkottai. The forecast also includes Nilgiris, Coimbatore, Tiruppur, Theni, Dindigul, Tenkasi, Virudhunagar, Tiruvannamalai, Kallakurichi, Perambalur and Ariyalur.

Tirunelveli Rain: Oothu gets 8 cm

Tirunelveli district recorded the highest rainfall among stations listed by IMD for the 24 hours ending on the morning of October 13. Oothu received 8 cm, followed by Nalumukku at 7 cm and Kakkachi at 6 cm.

Manjolai and Nanguneri each recorded 5 cm of rain. Ambasamudram, Manimuthar Dam and Manimutharu received 4 cm each, while Kodumudiyaru Dam, Tirunelveli AWS and Palayamkottai recorded 3 cm each.

IMD also lists 2 cm at several locations, including Kannadaian Anicut, Moolaikaraipatti and Papanasam. These are recorded rainfall figures, not forecasts for October 14.

Kanyakumari and Thoothukudi Rain

Several stations in Kanyakumari district recorded rainfall as per IMD. Pechiparai Agro, Adayamadai and Mullanginavillai received 4 cm each, while Kozhiporvilai, Kannimar and Thirparappu recorded 3 cm each.

In Thoothukudi district, Satankulam received 3 cm. Old Taluk Office in Srivaikuntam and Ettayapuram recorded 2 cm each. The IMD’s chief rainfall list also includes smaller amounts at other locations in the district.

These observations come as the IMD forecasts isolated heavy rain in Kanyakumari and Thoothukudi on October 14. The rainfall already recorded at individual stations does not mean every part of either district will receive the same amount in the next 24 hours.

Nagapattinam, Velankanni and Ramanathapuram rain update

Velankanni in Nagapattinam district recorded 5 cm of rainfall in the 24 hours as per IMD. Thirukuvalai received 3 cm, while Vedaranyam recorded 2 cm. Nagapattinam station recorded 1 cm.

In Ramanathapuram district, Mandapam received 3 cm and Pamban recorded 2 cm. Both districts are included in the wider rainfall outlook, although the October 14 heavy-rain warning specifically names Ramanathapuram, Thoothukudi, Tirunelveli and Kanyakumari.

Nagapattinam is also among the districts forecast to receive moderate rain on October 14. The district appears again in the heavy-rain warning for October 15.
