Rain likely across Tamil Nadu till 12 November; heavy spells in delta and south

Much of Tamil Nadu can expect a wet Deepavali, with rain likely across the State until 12 November and heavy rain forecast for the delta and southern districts until Tuesday, 10 November, The Hindu reported on 7 November.

In Tiruvannamalai district, water has been released from the Shenbagathoppu dam after heavy rain in its catchment. Collector Vandhana Garg has warned people living along the Kamandalam Naganathi river, in the towns of Polur, Arani, Cheyyar and Vandavasi, not to try to cross it while the flow is rising.

The rain follows the remnant of Cyclone Murasu, which weakened into a depression over east Telangana and coastal Andhra Pradesh on 4 November after crossing the Andhra coast. The India Meteorological Department (IMD) will issue its next extended-range outlook, for 13 to 19 November, on 12 November.

Why it matters

The showers are welcome. Tamil Nadu’s 15 major reservoirs are only about a third full, against 92% at this time last year, and the IMD expects November rain overall to be below normal. Heavy local downpours can still cause flooding in low-lying areas and fast-rising rivers, as in Tiruvannamalai.

Staying safe

Do not cross rivers, streams or flooded causeways when the water is rising, even on foot or by two-wheeler. Keep away from fallen power lines, and follow advisories issued by district collectorates.
